It is therefore an object of the present invention to create a protective coating for heavily loaded loom components that is more resistant to wear than the known protective coatings.

覆過程で形成されるなら、改善することができる。As is known, the carbide phase guarantees above all a high wear resistance. On the other hand, the oxide phase improves the slipperiness between the textile raw yarn and the component. However, the oxide phase also has high wear resistance. By embedding it in the metal phase, the disadvantage that oxide carbide is not very strong can be largely compensated for. This implantation and the adhesion strength of the protective coating to the component or substrate can be improved if the oxide particles are formed during the HVC (high velocity thermal spray) coating process.

置く。In order to increase the adhesion strength of the coating to a substrate made of hardened steel, the surface to be coated is first degreased with a solvent and then sandblasted with a granular material made of aluminum oxide (corundum, Al2O2). The particle size of Al2O2 is for example between 0.12 mm and 0.25 mm. The substrate is placed approximately 100 mm from a sandblasting source that accelerates the particles at a pressure of approximately 3 bar.
