传统陶瓷涂层在质量、能耗、以及环保等方面都存在一定的问题，针对这一现象，提出了预渗入法制备陶瓷涂层技术。即预先在坯体表面造出孔洞，将陶瓷复合粉料预先渗入到坯体表面的孔洞中，通过烧结，在金属表面制备一层具有优异耐磨性的衬瓷层。研究了造孔剂加入量、预烧工艺等参数对孔分布的影响规律，利用扫描电镜分析了预烧后坯体的孔洞分布规律和烧结后衬瓷层的显微组织，实验结果表明：造孔剂的加入量（淀粉）为10％、预烧工艺参数为400℃×1h时，坯体中孔的分布较为均匀，孔径大小适合纳米氧化锆的预渗入；预渗入法获得的衬瓷层厚度为50μm-150μm，烧结后的陶瓷颗粒被金属镍牢固包覆。

Arming at the problems of ceramic - coating made in the traditional method in quality, energy consumption, and environmental protection, the new technology lining - ceramic - layer in surface of metal calling prepermeating technique is puts forward into. Namely some holes would be pre -prepared in the surface of the green body, and the ceramic composite powder infiltrated into the hole, and then lining ceram- ic layer which has excellent wear - resistance have formed in the metal surface by sintering. It was studied that influence rule of two factor both the addition amount of the starch and pre - burn process parameters to distribution of the holes, analyzed the distribution state of hole on the surface of green body and microstructure of lining - ceramic - layer using SEM. Result show that hole distribution uniform in the green body, and its size suits for permeating of granule of zirconia under such experiment condition that starch contents for 10% , pre - burn temperature at 400℃ × 1 hour; the thick of lining ceramic layer is 50μm - 150μm, ceramic particle was coated by nickel metal after sintering.
