CERMET COATING, SPRAYING PARTICLES FOR FORMING SAME, METHOD FOR FORMING CERMET COATING, AND ARTICLE WITH COATING

Document Type and Number:

WIPO Patent Application WO/2011/065512

Kind Code:

A1

Abstract:

Provided is a cermet coating which can further effectively take advantage of the hardness of the powder used for forming a hard reinforcement phase. Also provided are spraying particles for forming the cermet coating. The cermet coating is a cermet coating formed on a surface of a base and comprises a hard reinforcement phase and a binder phase. The cermet coating is characterized by having a Vickers hardness which is 50 to 100%, excluding 100%, of the hardness of the powder used for forming the hard reinforcement phase, and by having a surface roughness (center-line average roughness, Ra) less than 3.0. The cermet coating is further characterized by being a coating formed by: heating spraying particles which are aggregates formed from both a powder for a hard reinforcement phase and a powder for a binder phase; and jetting the spraying particles against a base at a supersonic velocity to integrate the powder for a hard reinforcement phase with the powder for a binder phase.
