Deposition of DLC/oxynitriding Films onto JIS SKD11 Steel by Bipolar-pulsed PECVD

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...

Effect 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...

Investigation of Magnetite Thin-Films Produced by Pulsed Laser Deposition

Thin-films of magnetite, F@04 have been produced by the XeCl excimer laser ablation of both Fe304 and metallic Fe targets. The ablation of metallic Fe has been shown to produce about two orders of magnitude smaller concentration of boulders than the ablation of bulk magnetite. The use of single-crystal, latticematching substrates was found to be necessary at lower fluences (1 3 J cm-') for the ...

Pulsed Laser Deposition of Hydroxyapatite Thin Films

Pulsed laser deposition of VO2 thin films

High quality vanadium dioxide ~VO2! thin films have been successfully deposited by pulsed laser deposition without postannealing on ~0001! and ~101̄0! sapphire substrates. X-ray diffraction reveals that the films are highly oriented with ~010! planes parallel to the surface of the substrate. VO2 thin films on ~0001! and ~101̄0! substrates show semiconductor to metal transistions with electrical r...
