Recently, Cr-Al-N coatings have received more and more attention of researchers owing to its standing-out mechanical performances and superior chemical stability. In this present work, CrAlN ternary coatings were deposited by a bipolar pulsed dual magnetron sputtering (BPDMS) method and the effects of substrate negative bias on deposition rate, structure, hardness and adhesion of the coatings were investigated. The application of appropriate negative substrate bias voltage leads to dense structure, high hardness and excellent adhesion for CrAlN coatings.

ABSTRACTThe characteristics of RF bias-sputtered Al films are clarified. A negative substrate bias voltage, VDC, produced by RF biasing, strongly influences not only the planarization effect but also film characteristics such as hillock and void growth, and Ar content.Films deposited at VDc lower than -150 V. are significantly degraded due to the formation of two kinds of voids grown during annealing. One type is a blister-like voids, while the others are large and irregular. These are produced when Ar is released from the films during heat treatment. as evidenced by the fact that the amount of Ar released from the films rapidly increases when VDC is lower than -150 V.Although biasing strongly effects Al films resulting in the formation of an almost complete (111) texture. the effect degrades as VDC exceeds -200 V. Thus, Al bias sputtering requires a high resputtering rate and a VDC higher than -150 V to achieve appropriate planarization with suitable film characteristics.

LaB6 films are deposited by magnetron sputtering deposition. ZrO2 glass is used as substrate. Bias voltage and substrate temperature are adjusted. Morphology of films that deposited at different parameters is characterized by AFM. Results of AFM shows that grains diameter on surface of LaB6 films is nanoscale, and roughness of the surface is less than 20nm. LaB6 crystallites are seen to cover substrate surface entirely. Structure of films is smooth and compactness, and there is no obviously default is found. Bias-voltage influences morphologies of films more obviously than substrate. The best bias voltage is-100V. Structure of film that deposited at 450°C is more compactness than others, and roughness of the film is least.

The paper presents the results of the study on the influence of a high substrate bias voltage from 300 up to 1300 V on the titanium nitride coating deposition under nitrogen pressure of 2 Pa. The deposition rate, phase and chemical composition, adhesion and mechanical properties of coatings, macroparticle number and size distribution were investigated.
