Preventing Damage to Chrome Finish

Chrome is a type of surface finish wherein a thin layer of chromium is electroplated onto plastic or metal objects boost its resistance against corrosion and wear. It also gives the electroplated objects a nice shiny metallic finish.

 

A very thin film of chromium oxide forms on the surface of the chrome when it is exposed to air. The oxide layer seals the surface of the chrome and prevents further oxidation from occurring.

 

Yet there are particular instances that cancels the capacity of the chromium oxide in shielding chrome and the metal object from corrosion. Using very aggressive cleaners can remove the oxide on the surface. A new layer of oxide will be formed after cleaning as the exposed chromium reacts with the oxygen in the air. The repeated oxidation reactions can cause the chrome layer to become thinner over time. Instead of cleaners, lubricating oil can be used for cleaning chrome. The oil loosens up dirt with without removing the protective oxide.

 

Chips and scrapes on the chrome surface that exposes the metal underneath is very problematic. The exposed metal will rapidly oxidize. In the case of steel, the iron from the steel and the oxygen in the air forms rust.

 

The chipped or scraped area must be cleaned from any rust and recoated with chrome. The recoating process is complicated and can be very expensive. That is why it is important to prevent chipping or scratching of the chrome surface.  A lubrication product like oil can be used to improve the lubricity of the chrome surface to minimize the risk of chipping when other objects come in contact with it. The high lubricity means that objects are more likely to slip on top of the chrome instead of digging into it.

Basic Information On Friction Modifiers

The primary objective of a lubricant is to minimize friction between two or more surfaces of mechanical components. The term lubricity describes the ability of the lubricant to reduce friction. There are many instances where the base oil in the industrial grease or oil may not have the most suitable lubricity and simply adding more lubricant will not fix the issue. The friction modifiers are added to lubricants to alter the lubricity of the base oil, thereby meeting the demand of the application.

bearing-grease-high-speedFriction modifiers are compounds that change the coefficient of friction of lubrication products. In other words, these substances change the amount of power required to allow two or more surfaces to move past one another. There are friction modifying compounds. Some friction modifiers increase lubricity to improve efficiency. Others reduced lubricity to give mechanical components improved traction.

Decreasing the friction within a combustion engine enable parts to move more efficiently. This improves fuel economy. In transmissions, the role of the friction modifier is to increase friction as to protect against slippage when shifting gears.

There are lots of lubrication applications in which a specific quantity of traction is required for devices to run effectively. The friction modifiers employed in these applications are not intended to enhance or reduce friction but to cause the lubricant to act differently depending on the shear conditions.

Worsening of Static Oil Bleed

Oil bleed is something that all industrial grease suffer from. The bleeding or separation of oil from the thickener is a normal occurrence that can happen during service or storage. The bleeding that happens during service is what is known as dynamic oil bleed and happens due to mechanical stresses that the grease is exposed to. This type of bleeding is necessary for the grease to perform its lubrication duty. The movement of the bearings causes the oil to flow out of the thickener and into the surfaces that requires lubrication.

The bleeding that happens during storage is known as static bleeding. During storage, the weight of the grease creates a stress that causes the thickener to release oil. The less dense oil travels to the top of the grease and forms a puddle on the surface.

The separated oil can be removed or mixed back into the grease. The amount of oil that separates during storage is inconsequential to the performance of the grease. However, certain storage conditions can aggravate the bleeding to a level in which the performance of the grease is jeopardize.

Factors that can worsen static oil bleed are vibrations and temperature. The mechanical and thermal stress caused by these two activates the grease into releasing oil. Proper storage practices must be observed to prevent excessive oil bleed and protect the performance of the grease.

Applying Industrial Grease

Precision is very important when applying industrial grease. Too much grease volume can cause problems like high operating temperatures, seal ruptures and collapsed shields of bearings. This can also increase energy consumption and mechanical failures. Too little lubricant and bearing components wear out very quickly and eventually lead to failure.

Industrial GreasesThe grease guns are the unsung heroes of industrial grease application. These tools make it possible to apply precise amount of grease and deliver the lubricant to hard-to-reach lubrication points. Using a grease  gun is very straightforward. However, one must still pay attention to safety guidelines when using a grease gun to avoid injuries.

There are 4 main types of grease guns: manual, battery-operated, electric, and air-powered.  Manual grease guns are the most commonly used type of grease guns. These are affordable and are easy to maintain. Manual grease guns include pistol-grip models that are easy to hold. These grease guns can produce pressures up to around 10,000 kPa.

Also known as pneumatic grease guns, the air-powered grease guns rely on compressed air to force out the grease and into the lube point. The electric grease guns are used as an alternative to pneumatic variants and creates a consistent flow of grease. A corded electric grease gun is not ideal for applications that requires moving from one are to another.

The battery-operated grease guns perform similarly to an electric grease gun but are more handy. These can speed up lubrication applications and help minimize fatigue to lube technicians.

Lubricant for Cleaning

A lubricant has many functions aside from lubrication. Industrial lubricants are formulated to attain certain properties that makes them suitable for certain applications. Some are designed to handle intense heat while others are formulated to not coagulate when exposed to very low temperatures. Other lubricants offer high resistance to corrosion while others are designed for handling high loads.

Moisture is one of the greatest enemy of metals. It causes rusting or corrosion which damages metal the surfaces of components. If left unattended, the corrosion can get into so deep that the structural integrity of the metal object is compromised.

Regular wiping or brushing of oil on metal items helps protect against moisture and removes unsightly rust. The oil layer creates a barrier against air and moisture thereby preventing the metal surface from reacting with it. In the case of rusting, the oil sips into the deepest layer and helps loosen the rust buildup, making it easier to remove.

Some people mistakenly believe that protective coating processes are able to provide enough protection to metal. There are indeed coatings that are designed to protect metals from corrosion. Black oxide coating and chrome plating are two of the most commonly used methods for protecting metals. However, even these methods are not able to provide complete protection against damages caused by moisture.  If you look at chrome surfaces, you will see minor signs of corrosion. This is mainly because chrome plating is often applied thinly as thicker plating is more prone to chipping.

As mentioned, the only way to protect and preserve metal item is regularly cleaning and applying protective coating. A lubricant can do this two tasks.
