Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages. Key properties of grinding media are size, density, hardness, and composition. Size: The smaller the media particles, the smaller the particle size .

Introduction to Surface Hardening of Steels

Introduction to Surface Hardening of Steels

various diffusion methods (Table 2), gas carburi-zation is the most widely used, followed by gas nitriding and carbonitriding. Case hardness of carburized steels is primar-ily a function of carbon content. When the car-bon content of the steel exceeds approximately 0.65%, additional carbon has no effect on hard-ness but does enhance hardenability.

Oct 01, 2014 · It can make the part extremely hard with minimal deformation, he said. The result is achieved by diffusing nitrogen into the surface of the metal via three different methods: gas, salt bath and plasma. In gas nitriding, a heated part is exposed to a nitrogen-rich gas, typically ammonia, which diffuses onto the surface to create the nitride layer.

• The metal's condition. The heating rate for hardened (stressed) tools and parts should be slower than the heating rate for unstressed or untreated metals. • A metal part's size and cross section. To prevent warping or cracking, you need to heat large cross-sectioned parts slowly to allow the interior temperature to
