Abstract
In the present work, thin films of TiN were obtained on AISI 316L stainless steel substrates by DC unbalanced magnetron sputtering with promising characteristics such as resistance to wear and corrosion to be used in biomedical applications by changing the temperature of the substrate and the mixture. of gases. Microstructural characterization was performed using optical microscopy, atomic force microscopy, and scanning electron microscopy (SEM). Scratch tests were performed using an irradiated and non-irradiated ultra-high molecular weight polyethylene (UHMWPE) pin on the coated and uncoated substrates to study and compare the scratch effect, continuing the same circumferential geometry, a stroke length of 200 m and a 5N wet load using pure Milli-Q water (type 1) to simulate body fluids with the pin to test its performance and implant durability showing higher values in the coefficient of friction (COF) in the TiN-coated samples.
