Optimizing the efficiently used nickel ratio in nickel plating process by using response surface methodology

Efficient usage of nickel, one of the important cost parameters of nickel chrome plating processes, is compulsory for competing. In this study, it is aimed to optimize the process parameters of the nickel baths of a manufacturer that plates nickel-chromium on metal. For this purpose, response surface methodology (RSM), one of the experimental design and optimization techniques, has been used. In nickel baths; while maximizing the rate of nickel sticking to the surface of the workpiece; temperature, nickel sulfate (NiSO4) ratio, nickel chloride (NiCl2) ratio, boric acid (H3BO3) ratio, pH and polisher ratio were selected as factors affecting the process. At the end of the study, the efficiently used nickel ratio in the bathrooms was increased from 80% to 95%.

Nikel kaplama prosesinde verimli olarak kullanýlan nikel oranýnýn yanýt yüzey yöntemi ile eniyilenmesi

Nikel krom kaplama süreçlerinin önemli maliyet parametrelerinden biri olan nikelin verimli kullanýmý rekabet için zorunludur. Bu çalýþmada, metal üzerine nikel-krom kaplama yapan bir üreticinin nikel banyolarýnýn verimliliðini arttýrmak amacýyla, proses parametreleri eniyilenmeye çalýþýlmýþtýr. Bu amaçla, deney tasarýmý ve eniyileme tekniklerinden biri olan yanýt yüzey yönteminden (YYY) yararlanýlmýþtýr. Nikel banyolarýnda; iþ parçasýnýn yüzeyine yapýþan nikel oraný maksimize edilirken; süreci etkileyen faktörler olarak, sýcaklýk, nikel sülfat (NiSO4) oraný, nikel klorür (NiCl2) oraný, borik asit (H3BO3) oraný, pH ve parlatýcý oraný seçilmiþtir. Çalýþmanýn sonunda, banyolardaki verimli kullanýlan nikel oraný %80’den %95’e çýkarýlmýþtýr.
