Galling is a combination of friction and adhesive wear. It appears when two materials, which are pressed against one another by compressive force, are moved, causing friction. The materials are welded together by these compressive forces. Upon moving, particles of one material are removed and placed on the other. Galling is not to be confused with abrasive wear and cold welding, although it does display similarities with both.
Cobalt-Based alloys are materials whose cobalt-basis is alloyed with elements such as chromium, tungsten, nickel and iron. Along with nickel-based alloys, they are used in challenging environments including high temperatures and acids. While cobalt-based alloys are considered to be highly corrosion resistant, its durability can be further improved by applying BoroCoat® as a diffusion treatment.
In material science, strength of materials refers to the ability to withstand stress without breaking. There are different types of strength which are defined by the type of stress they can withstand. In this article, we will introduce you to the most common types of strengths, meaning the types of strengths that are most reflective of the amont of stress the component can endure during its application.
There are generally three of them:
