Investigation of the mechanical and corrosion properties of Ni-W/hBN composite coatings produced usi̇ng the elektrodeposition method.

It is known that nickel (Ni) has resistance to corrosion, hardness, ability to change size in magnetic field and adhesion force, and it has been seen in the examinations that tungsten (W) is used in hard, high melting temperature and crack removal method. In addition, a new Ni-W/hBN alloy composite coating material was formed by electrodeposition method using Hexegonal Boron Nitride (hBN) to increase its lubricity, hardness and corrosion resistance. In this study, by changing the amount of Poly Ethylene Glycol (PEG) of Ni-W alloy coatings obtained by using the electrodeposition method, four separate samples were obtained from a single bath and Ni-W/hBN coatings were obtained from a single bath by changing the amount of Hexagonal boron nitride (hBN). Four different samples were obtained and microhardness, surface roughness, corrosion resistance, optical microscope and XRD images between these samples were compared. As a result of these comparisons, it was observed that the adhesion of the third and fourth samples of Ni-W alloy coatings with changed PEG amount in the adhesion test was better than the first and second samples, and the adhesion of the first two samples from four different Ni-W samples obtained in the same bath was better than the third and fourth samples. has been observed. In the Ni-W/hBN bath, by increasing the amount of hBN, the adhesion ability of the third and fourth samples was better than the first and second samples, and the adhesion ability of the first three samples from four different Ni-W/hBN samples obtained in the same bath was better than the fourth sample. . It has also been observed that hBN particles added to the Ni-W bath play a major role in increasing the hardness.
