Study of wear rate of cutting tools made from Cr-based high-temperature alloy during operation depending on the material properties of the cutting tool and the rate of cutting

In the work, the wear rate of cutting tools made of hard alloy, cutting ceramics, and ultra-hard materials has been studied. The slowest wear rate is achieved using hard-alloy, with the bonding of hard-melting metal in the composition.

Chromonickel Alloy for Dies Used in Hot Stamping of Hard Materials

It is expedient to use a high-temperature chromium alloy in the manufacture of tools for hot stamping inelastic materials. The thermophysical and mechanical properties of chromium result in an alloys with high thermal stability and resistance to fatigue in thermal cycling.     

Wear resistance of a coated hard-alloy tool in the machining of high-temperature chromium alloys

The influence of the hard-alloy substrate and the composite coatings of a tool on its wear resistance in the machining of high-temperature chromium alloys is investigated. The effectiveness of the coated hardalloy tool is determined by the properties of the hard alloy and the coatings. For hard alloys characterized by relatively low strength and crack resistance, the coatings prove ineffective, on account of the brittle failure of the substrate and the consequent destruction of the coating. On alloys with low thermal stability, the coatings are ineffective on account of weakening of the binder at the high temperatures associated with machining. It makes sense to use a hard alloy with mechanical properties such that the coating may operate effectively. Better properties are not needed.
