- 摘要:
- 研究了 HEDP 镀铜时 0.4 g/L 添加剂 R 对镀铜溶液的润湿能力、分散能力、深镀能力的影响规律，并考察了 0.4 g/L 添加剂溶液在不同金属基体上获得的镀层的外观和结合力。结果表明：加入添加剂前后，溶液的接触角由 37.0° 降低至 24.5° ，添加剂的加入使溶液的润湿能力获得明显的改善；溶液中加入 0.4 g/L 添加剂后分散能力达到 80.18% ，高于未加添加剂溶液的 65.29% ，分散能力有所提高；溶液的深镀能力达到 100% ， 150 mm × Φ 7 mm 的盲孔管件内壁能够全部上镀；利用 0.4 g/L 添加剂溶液在不锈钢、硅青铜、铝合金以及钛合金上分别镀铜后发现，镀层具有良好的外观质量，热震后镀层未出现鼓包、破裂或脱落现象，镀层具有较高的结合力；铜作为打底层在不锈钢、硅青铜和铝合金上分别镀覆锡、锡铋和银后发现，镀层表面光滑平整，弯折及划格后发现镀层并未出现分层或脱落现象，镀层结合力良好。
- Abstract:
- ： The influence of 0.4 g/L additive R on the wetting ability ， dispersion ability ， and deep plating ability of the plating solution during HEDP copper plating was studied ， and the surface and binding force of copper coatings obtained by 0.4 g/L additive solution on different metal substrates were investigated. The results showed that the contact angle of the solution decreased from 37.0° to 24.5° after the addition of additives ， and the wetting ability of the solution was obviously improved. When 0.4 g/L additive was added into the solution ， the dispersing ability reached 80.18% ， which was higher than 65.29% of the solution without additive. The deep plating ability of the solution reached 100% ， the inner wall of 150 mm × Φ 7 mm blind hole pipe could be plated completely. After copper plating on stainless steel ， silicon bronze ， aluminum alloy and titanium alloy with 0.4 g/L additive solution ， it was found that the coating had good appearance quality. After thermal shock ， the coating did not bulge ， break or fall off ， which mean that the coating has a relatively high binding strength. After copper was used as the backing layer ， tin ， tin bismuth and silver were respectively plated on stainless steel ， silicon bronze and aluminum alloy ， it was found that the surface of the coating was smooth and flat. After bending and scribing ， it was found that there was no delamination or peeling off of the coating ， and the adhesion of the coating was good.
