Abstract
A number of articles on strengthening thin film coatings were analyzed and a lot of unusual strengthening effects, such as super high hardness and plasticity simultaneously, ultra low friction coefficient, high wear-resistance, curve rigidity increasing of drills with small diameter, associated with process formation of nanostructured coatings by the different thin film deposition methods were detected. Vacuum coater with RF magnetron sputtering system and ion-beam source and arc evaporator for nanostructured thin film coating manufacture are represented. Diamond Like Carbon and MoS 2 thin film coatings, Ti, Al, Nb, Cr, nitride, carbide, and carbo-nitride thin film materials are described as strengthening coatings.
Highlights
The main methods of strengthening coatings manufacture are PVD (Physical Vapor Deposition): ionplasma sputtering and ion-beam deposition and arc evaporation with the reactive gas inlet into vacuum chamber
Thin film coatings structure and the main characteristics of the coatings are determined by thin film deposition process
An important application of thin film deposition in machine building is the strengthening of cutting and deformation tools by applying wear-resistant coatings
Summary
The main methods of strengthening coatings manufacture are PVD (Physical Vapor Deposition): ionplasma sputtering and ion-beam deposition and arc evaporation with the reactive gas inlet into vacuum chamber. Vacuum coater with three types of sources – RF magnetron sputtering system, ion-beam source, arc evaporator – was elaborated for nanostructured thin film coating manufacture (Fig. 1). Wear-resistant and antifriction strengthening coatings are manufactured by means of PVD methods.
