Wear resisting parts for process valves

Wear resistant process valves, the process valves comprising:

• a coating disposed on surfaces of the valves subjected to wear, the coating having a thickness within a range of 50 to 500 μm;
• wherein the coating is produced by a thermal spraying method from a coating powder having a cemented carbide microstructure including at least two cubic hard material phases and a metal binder phase, each phase having a nucleus/shell structure of a hard material particle, the nucleus of the hard material phase primarily containing Ti and C and the shell of the hard material phase primarily containing Ti, a second metal and C;
• and
• wherein at least one additional alloying element is simultaneously contained either in the hard material phases or in the metal binder phase or in both, whereby the nucleus/shell structure of the cubic hard material phases is transferred to the coating and can be demonstrated therein.
