Properties, Peculiarities and Applications of Powder Coatings Formed by Multi-Chamber Detonation Sprayer

Abstract:

The paper describes the properties of Ti, Nickel-based, and Al₂O₃ powder coatings obtained through a new method of powder acceleration which allows to achieve the powder velocity of 1400m/s. The Ti-based coatings thus formed have nanocrystal and amorphous structure with nanodispersed ceramic compounds inclusions, and show the hardness of up to 16GPa, high plasticity and adhesion strength. The Nickel-based alloy coatings display both nanocrystal and amorphous structure. In ceramic Al₂O₃ coatings high spraying velocity allows filling in the space between the deformed oxide particles (about 0.053 microns in size) by nanocrystal and amorphous phases; thus, the coatings acquire a high degree of plasticity retaining high hardness of 1320 HV_0.3 with the porosity below 0.5%. The Al₂O₃ coatings were tested and found effective for covering the surface of porous metal matrixes in burners.
