Comparison of PVD and JVD / DVD Thin Film Coatings by Physical Vapor Deposition Methods and a Conceptual, Academic and Theoretical Analysis on Industrial Applications of DVD Coating Technology

Abstract Today, the fact that countries have effective and powerful weapons is directly related with technological developments in the defense industry. The national technology of an individual country is primarily measured by the development of the defense industry. Various coatings have been made using PVD, CVD, JVD/DVD, Plasma and Thermal spraying techniques in order to improve the quality of the systems which are exposed to friction, and so do not work, mostly results in loss of productivity in the industry. The aim of this study is to describe the basic differences of the direct vapor deposition (DVD) coating method, which is not yet implemented but is among the critical technologies in our country. Application of thin ceramic film coatings made by physical vapor deposition (PVD) method is frequently used in surface engineering applications where attention is paid on the superior technological features of the coating technologies. In this study, both coating methods were examined in terms of conceptual and system properties. By demonstrating the differences between the two methods, the applicability of the DVD method, which is shown as the coating technology of the future, has been investigated in our country. As a result, with the direct vapor deposition (DVD) technique; thin film coatings with superior properties effective on planar or curvilinear surfaces of alloys and compounds can be made on machine parts operating at high speed and therefore are expected to resist friction, abrasion and heat effects
