How to determine the coating weight of zinc phosphate coating
by Dr E Ramanathan Generally, thickness of different types of phosphate coating is reported as coating weight. Weight per unit surface area of phosphate coatings is calculated as follows: The coated specimen is weighed to the nearest mg (w1); the coating is removed by immersing the coated specimen in a 50 g/L chromic acid stripping…
