Plasma sprayed ceramic materials are mainly used, mainly aluminum oxide titanium and chromium oxide series oxide ceramics. This kind of material has high hardness, corrosion resistance, and certain toughness. It has excellent and stable wear resistance and wear reduction performance under the condition of insufficient lubrication and heat dissipation. The coating structure is dense, and the surface can be polished to an "orange peel"-like surface morphology with controllable roughness, and has an appropriate friction coefficient, so that the spinning fiber can obtain moderate twist and tension. At the same time, the coating has semiconductor properties, which can eliminate static electricity caused by fiber friction.
Chemical fiber, cotton spinning, glass fiber and other textile machinery, chemical fiber twisting spindle cup, chemical fiber hot roller groove, short fiber double twister wear-resistant accessories, and wear-resistant coatings for various spinning machine accessories.
1. AT3 (Al2O3/TiO2 97%/3%): Grey coating, good corrosion resistance.
2. AT20 (Al2O3/TiO2 80/20): The coating is dense, with high hardness and good toughness.
3. AT40 (Al2O3/TiO2 60%/40%): dense coating, good toughness, high bonding strength.
4. Cr2O3: High hardness, low friction coefficient, good corrosion resistance, abrasive wear resistance.
