Optimization of the Thermal Spraying Process Depending on the Surface Roughness

摘要

Nowadays, the requirements for the properties of machine parts are increasing. With this trend, the application of thermal spray coatings is also increasing in practice, with the aim of increasing resistance towards mechanical wear, corrosion, and oxidation, even at elevated temperatures. Research has been conducted in the field of machining for several years to increase efficiency in the machining process. This article is focused on the machinability of chromium - cobalt alloy called Stellite 6 produced using a high velocity oxygen fuel method (HVOF). The technology chosen was the shaping process. A total of 24 semi-finished products were machined under different cutting conditions. The results of the experiment are roughness values depending on the cutting speed, cutting depth and rake angle setting. Several graphs were created using statistical analysis showing optimal cutting conditions to obtain the best roughness values during the cutting process.
