Electrochemical Behavior of Dental Alloys after Surface Modification by Sputtering Coating Technique

For metallic materials, the corrosion behavior is the most important property to be considered due to the biocompatibility and cytotoxicity of the products of the corrosion process in vivo. Numerous coating processes have been developed to improve corrosion resistance, enhance the metal’s surface qualities, and increase its service life. The purpose of this review was to gather data on the corrosion of alloys in dentistry and plasma sputtering coating techniques to improve the surface characteristics of substrates. Several databases, including google scholar, pubmed, science direct, and web of science were searched electronically, and a manual search of the scientific literature was also carried out. Both searches were undertaken concerning this subject. This research provides a summary of the findings from seventy-seven studies that were conducted between the period from 2015 to 2025.We utilized the following keywords: “dental alloy, corrosion resistance, surface modification, sputtering coating technique”. According to the reviewed articles, Sputtering is an approach that is mostly utilized for the purpose of depositing various coatings in order to enhance the surface qualities of substrates. These properties include appearance, resistance to corrosion, resistance to wear, resistance to scratching, and biological compatibility.
