一种中温绝缘抗扭矩涂层及其涂覆方法
摘要：
本发明公开了一种中温绝缘抗扭矩涂层及其涂覆方法，该中温绝缘抗扭矩涂层由打底层(2)和中温绝缘陶瓷涂层(3)复合而成，并且打底层(2)设于金属基底(1)的表面与中温绝缘陶瓷涂层(3)之间；其中，所述中温绝缘陶瓷涂层(3)的厚度为100～200μm；所述打底层(2)的厚度为80～120μm，并且该打底层(2)的材料为镍铬、镍铝或镍铬铝。该中温绝缘抗扭矩涂层的涂覆方法依次包括预处理、打底层涂覆和中温绝缘陶瓷涂层涂覆的步骤。本发明实施例不仅具有优异的中温绝缘性能，而且具有良好的中温抗扭矩能力，能够有效避免陶瓷涂层在扭矩配合时从金属零件表面脱落。
摘要（英）：

The invention discloses a medium-temperature insulation anti-torque coating and a coating method thereof. The medium-temperature insulation anti-torque coating is formed by compositing a bottoming layer (2) and a medium-temperature insulation ceramic coating (3), and the bottoming layer (2) is arranged between the surface of a metal substrate (1) and the medium-temperature insulation ceramic coating (3), wherein the thickness of the medium-temperature insulation ceramic coating (3) ranges from 100 micrometers to 200 micrometers; the thickness of the bottoming layer (2) ranges from 80 micrometers to 120 micrometers, and the bottoming layer (2) is made of nickel-chromium or nickel-aluminum or nickel-chromium-aluminum. The coating method for the medium-temperature insulation anti-torque coating sequentially comprises the steps of pretreatment, coating of the bottom layering and coating of the medium-temperature insulation ceramic coating. The medium-temperature insulation anti-torque coating in the embodiment has the excellent medium-temperature insulation performance, has the good medium-temperature anti-torque capacity, and can effectively prevent the ceramic coating from being disengaged from the surface of a metal part during torque matching.
