- 摘要:
- 为了提高某型号发动机喷注器钎焊合格率,对影响喷注器钎焊质量的镍镀层厚度分布及其均匀性进行研究。通过对喷注器模拟件的试验,获得了在不同尺寸仿形阳极下喷注器孔内镀层厚度分布数据及电镀过程的电流密度分布图; 针对喷注器结构特点,设计出了喷注器电镀专用仿形阳极,确定了电镀过程中的阴、阳极间距。试验结果表明,在使用仿形阳极(外径170 mm、内径120 mm),阴、阳极间距控制在50 mm时,喷注器孔内的镀层厚度可控制在4～9.5 μm范围内,满足了产品钎焊使用要求,镀层厚度均匀性得到了有效控制。钎焊后的喷注器所进行2 MPa,10 min的气密性试验,结果较好,未出现渗漏等现象; 经对多台产品的适用性及稳定性研究,优化后的电镀工艺有着较好的稳定性,产品已通过试车及飞行考核。
- Abstract:
- In order to improve the brazing qualification rate of a certain type of engine injector, the thickness distribution and uniformity of the nickel coating which affects the quality of the injector brazing were studied.Through the test of the injector simulation, the data of the thickness distribution of the coating in the hole of the injector under different size profile anode and the current density distribution of the electroplating process were obtained.According to the structure characteristics of the injector, a special profile anode and the cathode-anode spacing were designed during the plating process.The test results show that when the profile anode(outer diameter 170 mm, inner diameter 120 mm)and the cathode-anode spacing are controlled at 50 mm, the thickness of the injector hole can be controlled within the range of 4～9.5 μm, which satisfies the product brazing and the uniformity of coating thickness was effectively controlled.The air-tightness test results of 2 MPa and 10 min were qualified after the brazed injector, and no leakage occured.Through suitability and stability of multiple products, the optimized electroplating process has a good stability, the product has passed the test and flight assessment.
