Investigation of Diamond Deposition on AISI 316 & 430 Stainless Steel Substrares
author
Abstract:
In this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (AISI 316) and ferritic (AISI 430) stainless steel substrates have been investigated using torch technique. The effects of substrate surface preparation has also been studied. The quality of coatings produced has been examined using optical and scanning electron microscopy, X-ray diffraction, Raman spectroscopy and atomic force microscopy.
The results obtained revealed very good crystalline grains and coating on austenitic and clusters of semi-and non-crystalline particles on ferritic stainless steel substrates. It was also observed that mechanical polishing and/or chemical etching would increase the nucleation density. The nucleation density was a function of substrate temperature, as well.

full textThe adhesion of hot-filament CVD diamond films on AISI type 316 austenitic stainless steel
Steel ball indentation and scratch adhesion testing of hot filament chemical vapour deposited diamond films onto AISI type 316 austenitic stainless steel substrates using two different interlayer systems, namely chromium nitride and borided steel, have been investigated. In order to compare the adhesion of these films with that of a well-known and strongly adherent system, detailed adhesion tes...

Abstract: Austenitic stainless steels exhibit a low hardness and weak tribological properties. The wear behaviour of austenitic stainless steel AISI 316 was evaluated through the pin on disc tribological method. For investigating the effect of wear on the changes in microstructure and resistance to wear, optical microscopy and scanning electron microscope were used. The hardness of the worn...

Surface texturing-plasma nitriding duplex treatment was conducted on AISI 316 stainless steel to improve its tribological performance. Tribological behaviors of ground 316 substrates, plasma-nitrided 316 (PN-316), surface-textured 316 (ST-316), and duplex-treated 316 (DT-316) in air and under grease lubrication were investigated using a pin-on-disc rotary tribometer against counterparts of high...
full textBiomaterial Studies on AISI 316L Stainless Steel after Magnetoelectropolishing
The polarisation characteristics of the electropolishing process in a magnetic field (MEP – magnetoelectropolishing), in comparison with those obtained under standard/conventional process (EP) conditions, have been obtained. The occurrence of an EP plateau has been observed in view of the optimization of MEP process. Up-to-date stainless steel surface studies always indicated some amount of fre...
