Preparation method of plasma spraying yttrium oxide coating on ceramic substrate
The invention relates to a preparation method of a plasma spraying yttrium oxide coating on a ceramic substrate. According to the method, atmospheric plasma spraying equipment is used for preparation. The preparation method comprises the following steps: (1) wiping a to-be-sprayed ceramic part by using isopropyl alcohol until the surface is clean, and ensuring that the surface is free of smudginess; (2) carrying out shielding treatment on the part, except for the to-be-sprayed area, of the ceramic part, and carrying out sand blasting treatment on the to-be-sprayed area after shielding; (3) shielding the ceramic part before spraying; (4) the part is subjected to atmosphere plasma spraying yttrium oxide coating preparation; and (5) measuring the film thickness of the ceramic coating, namely hanging the ceramic part and the aluminum alloy test piece together by virtue of a proper tool, carrying out the same sand blasting treatment and spraying treatment on the aluminum alloy test piece, and deducing the film thickness of the ceramic matrix coating by measuring the film thickness of the aluminum alloy test piece. The coating obtained by the preparation method has high compactness, high hardness, high tensile resistance, corrosion resistance and voltage resistance.
本发明涉及一种陶瓷基体上的等离子体喷涂氧化钇涂层制备方法，该方法使用大气等离子喷涂设备进行制备。制备方法为：(1)将所需喷涂的陶瓷零件使用异丙醇进行擦拭，擦拭洁净确保表面没有脏污；(2)将陶瓷零件所需喷涂区域以外部分进行遮蔽处理，遮蔽后对待喷涂区域进行喷砂处理；(3)将陶瓷零件进行喷涂前遮蔽；(4)对零件进行大气等离子喷涂氧化钇涂层制备；(5)陶瓷涂层膜厚测量办法，依靠合适的工装，将陶瓷零件与铝合金试片一同上挂，并对铝合金试片进行相同的喷砂处理与喷涂处理，通过测量铝合金试片的膜厚来推断陶瓷基体涂层的膜厚。该制备方法获得的涂层具有高致密性，高硬度，高抗拉伸性，耐腐蚀性以及耐电压性。
