摘要

本文的目標是塑膠元件使用表面處理方法，使元件具有較佳的機械性質。所以本文利用無電鍍方法為塑膠元件做表面處理，使塑膠元件上披覆一層薄薄的鎳磷鍍層，具有耐磨耗的特性。無電鍍的前處理包含除油、粗化、敏化活化等過程。本文分別在粗化過程中討論不同砂紙號數及敏化活化過程中討論不同浸泡時間與次數，以探討鍍層的表面附著力及厚度、以及不同pH值鍍液的鍍層效果之比較。在理論分析方面，並利用ANSYS軟體建模型進行力學行為分析，利用實驗與理論方法求取試片受拉力時的破壞力及最大剪應力，利用MTS拉伸試驗機求得試片受拉力時的破壞力，藉由實驗的破壞力代入ANSYS分析模型中求得鍍層的最大剪應力，並由理論分析值與實驗數據進行比較，證明理論分析正確性。最後，利用實驗方法與過程制定出最佳鍍層參數及實驗程序。

The purpose of this study was to apply surface treatment methods to provide favorable mechanical properties in plastic materials. In this study, we applied electroless plating technology to the surface treatment of plastic materials, such as plastic components that are Ni-P plated on surfaces to improve wear resistance. The pretreatment processes of electroless plating include oil removal, roughening, and sensitization/activation. This paper discusses the effects of applying various sandpapers to plastic materials. In the sensitization/activation process, the number of soak take the bath affects the surface adhesive force and thickness of the plating; therefore, this paper discusses the effect of different pH values involved in the sensitization/activation process. In the theoretical analysis, this study also used ANSYS analytic software to analyze the mechanical behavior of Ni-P plating. In addition, experimental and theoretical methods were applied to study the failure loads and maximal shear stresses of specimens under tensile loading conditions. Failure loads are determined using an MTS testing machine. The proposed ANSYS analytic methods, combined with experimental failure loads, are used to predict the maximal shear stresses of Ni-P plating specimens. The experimental results are then used to verify the accuracy of the proposed analytical methods. Finally, this paper summarizes the experimental methods and processes to determine the optimizing process parameters.
