Type: article
Abstract: This study investigates impact of titanium dioxide and chromium oxide coatings on 17-4 PH stainless steel components, comparing samples produced through Additive manufacturing and Conventional manufacturing methods. SEM analysis is performed to evaluate the impact of coatings on performance of 17-4 PH stainless steel components. The study examined the microstructure and wear behavior of titanium dioxide and chromium oxide coatings on precipitation hardening martensitic stainless steel (17-4 PH), which is widely used in the oil and gas industries. Macro Hardness test is also performed on both AM and CM with Chromium oxide and Titanium dioxide Coatings and they are compared with noncoated samples. The use of titanium dioxide and chromium oxide coatings significantly improved these properties in both instances. SEM and EDS were used to analyse the microstructure of material and its wear mechanisms. XRD study also done to obtained information about phase composition of feedstock powders. The wear tests were conducted utilizing a pin-on-disc tribometer equipped with pins that had various coatings. The wear resistance exhibited considerable variation attributed to the differing coatings on the pins. The study provides insights into optimizing stainless steel components for enhanced durability in harsh environments.
