Micro Structural and Mechanical Properties of Wear Resistant Coatings on Cast Iron Lathe Machine Slides and Beds

Abstract

Surface damage incurred during translational sliding doesn't entail the formation of deep grooves due to asperity penetration or foreign particle intrusion. Instead, sliding wear is characterized by the relative movement of two even solid outsides under load. These exteriors may either be lubricated or not lubricated, metallic or non-metallic. The abrasive and fatigue wear experienced by slides and lathe beds considerably diminishes their longevity. The study's goal is to extend the beds' and slides' useful lives. An examination of WC-Co-Cr and Al2O3 + 40TiO2 coatings sprayed by a detonation gun (D-Gun) on bare metal couches and shots of a cast iron imitation lathe machine is performed. The ASTM G99 standard was used to conduct the wear tests on pin-on-disc devices for both coated and uncoated cast iron samples. The findings indicate that the detonation gun spray procedure was successful in depositing WC-Co-Cr and Al2O3 + 40TiO2 coatings onto the cast iron. When compared to the material that was left uncoated, the coated material has exposed significantly less attire loss. Detonation-sprayed coatings lose more weight over time as the load grows. The wear on the WC-Co-Cr coating has been minimal. As a result, cast iron coated with WC-Co-Cr has less wear than Al2O3 + 40TiO2 coated and uncoated cast iron.
