Web2 days ago · The high degree of ductility present in nickel steels is complemented by the high strength, finer grain size, deep hardening, and wear-resistant properties imparted by the addition of chromium. The increased toughness makes these steels more difficult to machine than the plain carbon steels, and they are more difficult to heat treat. Traditionally, the wear of materials has been characterized by weight loss and wear rate. However, studies have found that wear coefficient is more suitable. The reason being that it takes the wear rate, the applied load, and the hardness of the wear pin into account. Although, measurement variations by an order of 10 … See more The wear coefficient is a physical coefficient used to measure, characterize and correlate the wear of materials. See more • wear rate • weight loss See more Materials science See more The steady-state wear equation was proposed as: $${\displaystyle V=K{\frac {PL}{3H}}}$$ where $${\displaystyle H}$$ is the Brinell hardness, $${\displaystyle V}$$ is the volumetric loss, $${\displaystyle P}$$ is the normal load, and See more • Nam P.
