Abstract

Three stainless steel mass standards of different grades each of mass 100 g were studied under normal ambient conditions by ellipsometry to determine the surface layers formed on them. The studied specimens are of grades E1, E2, and F1. The factors influencing the thickness of the surface layers were discussed. It was observed that the thicknesses of formed layers on different mass standards were not equal. The estimated values of the oxide and water layers range between 1 nm and 5 nm.
