Abstract
A powder material of the present invention contains ceramic-metal composite particles, wherein at least a part of the composite particles exhibit no breaking point in a stress-strain diagram obtained by applying a compressive load that increases up to a maximum value of 10 mN or more at a loading rate of 15.0 mN/s or less.

A powder material comprising ceramic-metal composite particles, wherein at least a part of the composite particles exhibit no breaking point in a stress-strain diagram that is obtained by applying a compressive load that increases up to a maximum value of 10 mN or more at a loading rate of 15.0 mN/s or less.
A powder material comprising ceramic-metal composite particles, wherein
- at least 10% of the composite particles exhibit no breaking point in a stress-strain diagram that is obtained by applying a compressive load that increases up to a maximum value of 200 mN or more at a loading rate of 15.0 mN/s or less,
- the composite particles each include ceramic particle portions containing tungsten carbide and metal particle portions containing cobalt, nickel, iron, or chromium, the composite particles have a ratio of an average diameter of the metal particle portions to an average diameter of the ceramic particle portions of less than 1,
- the average diameter of the metal particle portions is 1 μm or less,
- a ratio of the average diameter of the metal particle portions to the average diameter of the composite particles is 0.1 or less, and
- the composite particles each include pores having a median diameter of 2.0 μm or less.
