DETERMINATION OF THICKNESS OF SILVER COATING BY METHOD OF X-RAY FLUORESCENCE ANALYSIS
Methods of determination of thickness of plated silver coating deposited on ribbed bronze wall by method of x-ray fluorescence analysis is developed and dependence of coating thickness against concentration of silver is received. Critical coating thickness – boundary of applicability of method – is determined. Experimental test of methods by determination of coating thickness on ribbed walls of real production units is conducted.
Keywords: liquid rocket engines, cooled walls of chambers, electroplated coatings, contact-reactive brazing, x-ray fluorescence analysis.
