Deposition of DLC/oxynitriding Films onto JIS SKD11 Steel by Bipolar-pulsed PECVD
Traditionally, JIS SKD11 tool steel is corresponding to the AISI D2. Since this material possesses high hardness and excellent wear resistance, it is usually used as a mold material and cutting tools.1,2) In order to improve the tool life, many studies have focused on surface treatment as a method of protecting the internal material.2) Nitriding is a thermo-chemical process with nitrogen diffus...
متن کاملCOMPARISON OF PROPERTIES OF TiN/TiCN AND PLASMA NITRIDING/TiCN FILMS DEPOSITED ON THE TOOL STEEL BY PULSED DC- PACVD
In this work, TiN/TiCN & PN/TiCN multilayer films were deposited by plasma- assisted chemical vapour deposition (PACVD). Plasma nitriding (PN) and TiN intermediate layer prior to coating leads to appropriate hardness gradient and it can greatly improve the mechanical properties of the coating. The composition, crystalline structure and phase of the films were investigated by X-ray d...
متن کاملEffect Of Bipolar Pulsed Voltage On Properties Of DLC Films Deposited By Inductively Coupled PECVD
Diamond-like carbon (DLC) is a metastable form of amorphous carbon having large sp 3 bonding. DLC films have unique properties such as high hardness, low-friction, good transparency in IR region, chemical inertness and biocompatibility. To have better performance of the coating one should have proper selection of different parameters for deposition. In the present study, DLC films were deposite...
متن کاملEffect of PECVD Deposition Parameters on the DLC/PLC Composition of a-C:H Thin Films
Filmes finos de carbono amorfo hidrogenado (a-C:H) têm sido depositados na superfície de materiais para melhorar propriedades mecânicas, ópticas e químicas. Nesse estudo, foi empregado o sistema de deposição química assistida por plasma (PECVD) para sintetizar filmes de a-C:H com fases DLC (tipo diamante) e PLC (tipo polimérico). As pressões parciais de acetileno em argônio foram variadas e as ...
