摘要

本實驗使用商用純鈦電解形成氧化鈦顆粒於電解槽中，將不同濃度的二氧化鈦顆粒與鍍鎳成分調製成鍍液，並在不同攪拌速率及直流或脈衝電流密度進行複合電鍍，分析鍍層中二氧化鈦顆粒含量及結構與表面型態對微硬度及耐腐蝕性影響。結果顯示，微硬度及耐腐蝕性的增加，都與鍍層內陶瓷顆粒平均含量增加而增加有關。另外，此製程方式的優點，在於使用電解方式備製陶瓷顆粒可均勻分散於鍍液中，且鍍浴中顆粒含量濃度及性質的改變與製作成本均可以控制，因此非常適合於複合電鍍工業之發展，也增加產業競爭能力。

The experiment produced composite coating with Ni-base material ingredient and different TiO2 concentration, stirring rate of electrolyzed commercial pure titanium formed TiO2 particles into the electrolyth bath which was used distinct direct or pulse current density, then analyzing the coating of TiO2 particles contents, surface morphology and structure to the effects of microhardness and corrosion resistance. As a result, we found microhardness and corrosion resistance will increase. The result was that TiO2 particles in the composite coatings increasing with average content. Besides, the advantages of the process was using electrolysis could dispersed TiO2 particles into the Electroplating solution with easily change to the particles content and properties. The most important thing was saving the cost of process. Therefore, it will increase the capability of competition in composite plating industry.
