Parts cleaning before and after heat treatment of metals
In recent years, the importance of cleaning surfaces before and after heat treatment of metals has increased with respect to the required quality of their surfaces. The cleaning process is a necessary manufacturing step, which ensures the function of engineering component and which is also reflected in the cost of heat treatment. Increasing surface quality requirements before chemical heat treatment operations as well as growing awareness of the effect of poorly cleaned surfaces on diffusion processes result in an increasing complexity of the cleaning process. The report provides an overview of the state of the art technology taking into account the necessary analysis of the cleaning process in relation to the part, the nature of the impurities and their quantity, the parameters of the process, and the choice of suitable washing detergent.
