本研究以非平衡磁控濺鍍被覆添加金屬之碳氮鍍層為研究材料：分別添加鉻金屬、鎢金屬、鈦金屬和鋯金屬。針對上述四種添加金屬之碳氮系列鍍層，研究其特性、各項機械性質、接觸角、抗腐蝕能力…等。培養金黃色葡萄球菌以進行抗菌能力的測試，最後綜合分析各項性質對抗菌能力的影響。
實驗得到以下一系列結果：表面粗糙度在奈米等級下對抗菌效率沒有直接的影響，推測原因為因為細菌大小在0.5μm-1μm之間，奈米尺度的表面粗糙度所形成之坑洞不足以讓細菌殘留。在接觸角方面，接觸角度越大，抗菌效果也越好，接觸角度越大，其表面越是疏水，細菌不容易在鍍層表面滯留。抗腐蝕能力方面，腐蝕電位越大抗腐蝕能力越好，因為抗腐蝕能力越好，表面形成坑洞而造成細菌殘留堆積的情況也跟著減少。CN15Cr2A鍍層上經24小時培養後細菌的殘存量，為抗菌性最好的試片，抗菌性高達84.3%，而接觸角為94.90˚，腐蝕電位為-0.119V，疏水性的表面，高抗腐蝕能力，完全遵循上述研究結果。

ZrCN WCN CrCN TiCN and CN coatings, deposited by reactive magnetron sputtering, were investigated as possible to be used as protective layers on medical implants. Adds support for the four series of metal carbon coating, study its properties, the mechanical properties, contact angle, corrosion resistance ... and so on. S. aureus culture for testing antimicrobial activity, and finally a comprehensive analysis of the impact of the nature of the antimicrobial capabilities.
A series of experiments the following results: The surface roughness in the nanometer level has no direct effect on the antibacterial efficiency, presumably due to the size of the crater because the bacteria in 0.5μm-1μm between nanoscale surface roughness formed by the inadequate to allow residual bacteria. In terms of the contact angle, the greater the contact angle, the better antibacterial effect, the greater the contact angle, the more hydrophobic surface, bacteria are not readily retained in the coating surface. Anti-corrosion ability, the greater the corrosion resistance, the better the corrosion potential capacity, because the better the corrosion resistance, the surface of the crater caused by the accumulation of residues in the case of bacterial reduction followed. The residual amount of bacteria after 24 hours culture on CN15Cr2A coating, as best antimicrobial test pieces, antimicrobial 84.3%, and the contact angle 94.90˚, the corrosion potential of -0.119V, hydrophobic surface, high resistance to corrosion ability to fully comply with the above findings.
