Embodiment 1
[0016] Embodiment 1. A hydrocarbon-coated cermet powder, the weight percentage of each component is: refined starch: 0.5%; 200 mesh Ni-based alloy powder: 99.5%, wherein the Ni content in the Ni-based alloy powder is 80% ﹪.
[0017] The specific operation steps of the preparation method of the hydrocarbon-coated cermet powder are as follows:
[0018] A. Put the selected refined starch and boiled purified water into a container and stir to form a paste;
[0019] B. Mix the paste-like refined starch with 200 mesh Ni-based alloy powder, and then fully stir the mixture;
[0020] C. Put the mixed powder in an oven, dry the water at 100°C, then crush it with a mixer, and then sieve it with an 80-mesh sieve to make -80-mesh hydrocarbon-coated cermet powder.
[0021] Hydrocarbon-coated cermet powder was flame-sprayed on 20# steel plate. The particle size of the powder was -80 mesh. Sample test results: The thermal spraying effect of hydrocarbon-coated aluminum powder was good, and t...
