本實驗以(PC/ABS)為基材，以線徑2.0mm的鋅線為金屬披覆材，分三階段進行。第一階段旨在找出適合鋅金屬熔射製程起弧穩定最佳參數，第二階段找出噴塗製程的最佳參數，第三階段著重在前處理製程的差異性與熔射製程的影響。第一階段以(電壓值及線材送線速度與電流穩定度做比較)為製程參數。找出最佳起弧參數值後，第二階段以（噴塗距離及噴槍移動速度對未噴砂的基材）做比較找出最佳噴塗參數。第三階段加入前處理製程，噴金剛砂(不噴砂、60號砂、120號砂)做表面粗化、表面潔淨(不水洗、超音波震盪一分鐘、超音波震盪六分鐘)、去除水氣(不烘乾、烘乾溫度設60度烘乾時間一小時)。找出最佳前處理製程參數後，進行塗佈製程。之後測試基本性質(厚度、導電值、增加重量)，之後做機械性質測試(衝擊、抗拉、附著力測試)，並做顯微觀察 (SEM)。第一階段實驗結果發現，噴塗距離最好為二十公分，噴塗時氣壓需再0.6MPA以上，噴塗最佳電壓值為28伏特，噴槍移動最佳速度一秒十公分，送線速度為一秒10.3公分。 第二階段實驗結果發現，無烘乾下附著力，120號砂﹥60號砂﹥無噴砂，六分鐘﹥洗一分鐘 ﹥無清洗，有烘乾下附著力，60號砂﹥120號砂﹥無噴砂，六分鐘﹥洗一分鐘 ﹥無清洗，烘乾完後對附著力有顯著的影響，機械性值可增加60%的衝擊力。

This experiment takes (PC/ABS) as a parent metal, the material take the line diameter 2.0mm zinc line as the metal, divides three stages to carry on. The first stage is for the purpose of discovering suits the zinc metal melt to shoot the system regulation to get up the arc stable best parameter, the second stage discovers the spray coating system regulation the best parameter, the third stage emphatically processes the system regulation in front the difference and the melt shoots the system regulation the influence. The first stage (delivers link speed and electric current stability take voltage value and line material makes comparison) as the system regulation parameter. After discovers is best the arc parameter value, the second stage (is away from and spray gun traveling speed by spray coating to sand blasting parent metal) has not made the comparison to discover the best spray coating parameter. Front the third stage joins processes the system regulation, spurts the emery (not to sand-blast, 60 granulated substance, 120 granulated substance) makes the superficial coarsening, the surface purely (laundering, supersonic wave does not shake minute, supersonic wave shakes six minutes), the elimination moisture (does not dry, drying temperature supposes a 60 degree drying time for hour).After discovers best front processes the system regulation parameter, carries on spreads the cloth system regulation. Afterwards tests the basic nature (thickness, electric conduction value, increases weight), afterwards makes the mechanical property test (impact, anti-pulls, adhesion test), and makes the microexamination (SEM).The first stage experiment result discovered, the spray coating is away from well is 20 centimeters, when the spray coating the barometric pressure must above 0.6MPA, the spray coating best voltage value be again 28 volts, the spray gun moves optimum velocity second ten centimeters, delivers the link speed is second 10.3 centimeters. The second stage experiment result discovered that, it does not have the adhesion under drying, 120 granulated substance＞60 number granulated substance＞without sand-blasting, six minutes＞wash a minute ＞without cleaning, it has x the adhesion the adhesion, 60granulated substance＞120 number granulated substance＞without sand blasting, six minutes＞wash with one minute＞without cleaning, after dries has the remarkable influence to the adhesion, mechanicalness value may increase 60% impulse.
