Wear can be defined as the loss of material by action of another substance. There are generally three types of common wear: adhesive, abrasive and fretting. Each type of wear involves loss of material due to two or more surfaces interacting with another.

Decreasing the amount of wear can be affected by several factors including substrate selection, surface preparation and the metal finishing process. The hardness of the substrate can affect wear. However, the cost of the substrate can offset the savings in wear. With surface preparation, the smoother the surface, the less wear. Finally, the metal finishing process can affect wear depending on which metal finish is chosen. With today’s technology, there are many different finishes and coatings that can be used as well as combinations of technology.

One of the most prevalent modes of failure is corrosion. Corrosion is the degradation of materials’ properties due to interaction with their environment. Understanding the affects of corrosion requires reviewing the type of corrosion, rate of corrosion, extent of corrosion and the interaction between the corrosion and other failure modes.

Decreasing the amount of corrosion can be affected by several factors including substrate selection, surface preparation and the metal finishing process. Depending on the type of corrosion and the effect of the environment on the corrosion rate, the substrate selection can be critical. While there are many substrates available, the cost of the substrate may offset the savings.

With general or pitting corrosion, the failure mode begins when there is metal loss. Surface preparation is critical to reduce any areas where premature metal loss may be a factor.

Finally, the metal finishing process can affect wear depending on which metal finish is chosen. With today’s technology, there are many different finishes and coatings that can be used as well as combinations of technology.

A company’s reputation can be tied directly to the cosmetic appeal of their product. When it comes to chrome and other highly decorative finishes, it is critical to provide a “mirror-like” finish. Cosmetic specifications have improved significantly yet they are still subjective.

Lincoln Industries has had over 20 years working with customers whose reputation is based on their look. We provide highly-cosmetic parts to several of the largest custom motorcycle manufacturers in the country. We also supply chrome exhaust stacks and bumpers to the heavy truck market.

We understand what you need when it comes to highly aesthetic parts.

High temperature can be the cause of several failure modes including discoloration and accelerated corrosion. Today’s stringent EPA regulations often cause mechanical parts to operate at higher temperatures which can be both beneficial and detrimental to a system depending on the ideal situation.

There are typically three types of heat: conduction, convection and radiation. In simple terms, conduction is the transfer of energy through matter from particle to particle, like the warming of a cold spoon in a hot cup of soup. Convection is the transfer of heat by the actual movement of the warmed matter. If different parts of an isolated solid are at different temperatures, heat will flow from the hot places to the cold ones until eventually all is at the same temperature. For example, a hot cup of coffee cooling to room temperature. Radiation is the electromagnetic waves that directly transport energy through space. Heat from the sun reaches us as radiation, much of it visible light, the rest similar electromagnetic waves but at wavelengths our eyes are not sensitive to.

In some instances, it is best to keep as much heat inside a system for as long as possible. Other times, the goal is to dissipate heat as quickly as possible. As with each of the challenges that are presented to us, we use the Integrated Finishing Services™ philosophy to solve the challenge.

Lubricity is needed to minimize heat buildup and wear which accelerate failure. The phosphorus content in some metal finishes, or combination of finishes, allows for increased lubricity as well as increased corrosion protection.

Lincoln Industries uses its Integrated Finishing Services philosophy to review the entire manufacturing process from a new perspective. Working with the customer to understand the ultimate goal and applying our vast knowledge of metal finishing processes allows us to bring a solution to these difficult challenges.
