摘要: The invention relates to a coating powder and method for its production. Said powder can be used in many technical fields, specially in machine and vehicle construction in chemical and petro-chemical installations. This coating powder has a hardmetal-like microstructure and consists of two cubic hard material phases, each of them representing a nucleus-external surface structure of a hard material particle. The hard material phase in the nucleus contains mostly Ti and C and the hard material phase in the external surface mostly Ti, a second metal and C, which are embedded in a binder phase containing at least one or more elements such as Ni, Co and Fe. According to the invention, said coating powder is characterized by the fact that no additional alloying element exists either in the hard material phase, in the binder phase or in both phases simultaneously. According to the invention, the coating powder is produced by crushing and mixing and homogenizing the individual hard materials and the metal powder in an aqueous suspension in a ball triturator, which are later on granulated, sintered and processed using a grinding technique.

摘要: The invention relates to wear resistant parts for process valves. The use of said parts can be particularly advantageous in the chemical and petrochemical industry, in the mining industry and in other processing industries. According to the invention, the wear resistant parts for process valves are characterized by a 50 to 500 &mgr;m thick coating applied by thermal spraying on the valve surfaces subjected to wear, particularly on the bearing and sealing faces. The coating is characterized by the fact that one or more cubic hard material phases containing Ti and/or Ti and a second metal and a metal binder phase can be demonstrated therein, and by the fact that when the coatings are rubbed against each other within a temperature range of from room temperature to 600° C., the friction coefficient is
