High-entropy alloy powder material for supersonic spraying and manufacturing method thereof

The invention relates to a high-entropy alloy powder material for supersonic spraying and a manufacturing method thereof. The high-entropy alloy powder material for the supersonic spraying can be obtained and is characterized in that the high-entropy alloy powder material comprises, by atomic percent, 10-20% of Al, 15-20% of Fe, 15-20% of Co, 15-20% of Ni, 15-20% of Cr and 15-20% of Cr, and total percent is 100%. The high-entropy alloy powder material is made by a gas atomization rapid solidification process. Particles of high-entropy alloy powder are spherical or ellipsoidal, a phase structure is composed of a solid solution phase with a simple face-centered cubic or body-centered cubic structure, ingredients and tissues are even, alloy solid solubility is high, and segregation is small. The manufacturing method of the high-entropy alloy powder material is controllable in powder size, good in mobility, low in oxygen content, small in environment pollution, high-entropy alloy coating with excellent combination property or a block high-entropy alloy material with more excellent performance can be obtained through a supersonic spraying process.
