Wear resistance of carbon steel with different types of hardening

The wear resistance of carbon steel with different types of hardening, including steels with plasma hardening and carbonitriding, has been investigated. It was revealed that ShKh-15 steel is two orders of magnitude greater than as steel 15 and 45. This gives grounds to consider its application in both the traditional hardened condition and the normalized condition. The plasma hardening of steel 45 and carbonitriding of steels 15 and 45 yields an increase by dozens of times for both the wear resistance of disks made from steel and mating blocks of normalized steel 45. This will allow one to solve the problem of wear resistance for friction units by avoiding expensive alloy steels by using carbon steels with plasma hardening and carbonitriding. Finishing operations may be used as the latter, and a decrease will occur in labor hours along with an increase in durability.
