Composite ceramic coating adaptive to motor insulation bearing and preparation method of composite ceramic coating
The invention discloses a composite ceramic coating adaptive to a motor insulation bearing. The composite ceramic coating comprises a metal transition layer, a ceramic insulation layer and a polymer sealing layer, the metal transition layer is formed by spraying an alloy composed of 93wt% of Ni and 7wt% of Al, the ceramic insulation layer is formed by spraying a compound raw material, the compound raw material is formed by mixing mixed powder and a cellulose acetate binder accounting for 0.5% of the mass of the mixed powder, the mixed powder comprises 95-99wt% of alpha-Al2O3, 0.2-2.5 wt% of SiO2 and 0.2-2.5 wt% of CeO2, the thickness of the macromolecular sealing layer does not exceed 50 microns, and the raw materials of the macromolecular sealing layer are alkyd resin modified organic silicon impregnating varnish and a diluent. Through selection of coating materials and improvement of a spraying processing technology, the high-performance composite ceramic coating which is high in bonding strength with a bearing base body, high in toughness, not prone to stripping, high in density, wide in temperature application range and low in cost is prepared.
一种适配于电机绝缘轴承的复合陶瓷涂层，包括金属过渡层、陶瓷绝缘层和高分子封闭层，金属过渡层由93wt%的Ni和7wt%的Al组构成的合金喷涂而成，陶瓷绝缘层由复配原料喷涂而成，复配原料由混配粉末和混配粉末质量0.5%的醋酸纤维素粘结剂混合制成，混配粉末包括95‑99wt%的α‑Al2O3、0.2‑2.5wt%的SiO2和0.2‑2.5wt%的CeO2，高分子封闭层的厚度不超过50μm，其原料为醇酸树脂改性有机硅浸渍漆和稀释剂。本发明通过涂层材料的选择和喷涂加工工艺的改进，制备一种与轴承基体结合强度高、韧性强、不易剥落，致密度高，温度适应范围宽，且成本低廉的高性能复合陶瓷涂层。
