Thickness of alloyed layer in aluminum-diffusion-coated steel which prepared by packing method was determined by such methods as microscopy, electromagnetic, micro-hardness and electrolytic tests. Some degrees of scatter in the data are observed.
Width of scatter in within the order of 1/100mm even in this laboratory experiment., It is, therefore, reasonable that thickness of the alloyed layer could be determined with order of 1/10mm in commercial practice.
