ESTIMATION OF TECHNICAL CONDITION OF METAL PRODUCTS USING ROCKWELL HARDNESS TEST METHOD
Abstract
The value of Rockwell hardness of the metal layer obtained by a single measuring is considered in this paper as a random variable. A study of the random variable distribution is described including the technical condition of the metal surface. A series of Rockwell hardness tests is presented to estimate its main parameters. It is assumed that the hardness distribution refers to the lognormal distribution class. A comparison of results obtained from mechanical and optical and visual tests shows that the technical condition of metal products can be estimated using the Rockwell hardness test method.
