HEAT TREATMENT OPTIMIZATION ON THE WEAR BEHAVIOR OF A LOW STEEL NI-B-CNT ELECTROLESS COATING ALLOY

ABSTRACT: This work aimed to conduct a statistical analysis of the influence of heating treatment. Using the response surface methodology (RSM) technique, which is based on a core composite design, factors such as temp, deposition duration, and amount of CNTs on the wear behavior of electroless coatings (Ni-B-CNT and Ni-B) on low-alloy steels were investigated. The impacts of the heating treatment temp and deposition duration on the wear rate were evaluated for specimens heated to various CNT amounts (0, 35, and 0.7%). Specimen wear is accelerated by increasing the temperature and deposition duration between 350 and 400 degrees Celsius and then increasing the deposition temperature between 400 and 450 degrees Celsius. The wear rate of materials depends on several material and feature properties, including the topography, hardness, and frictional coefficient, in addition to the wear test conditions.
