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...

Stainless steel 316L has widely used as bioimplants in cranial plates, dental implants, bone fracture fixation, prothestic joints. However, low wear resistance, in some cases susceptibility to pitting and crevice corrosion in body environment and release of toxic ions from the surface are the basic disadvantages which this material prone to be. It has still applied as a temporary biomaterial du...

The aim of the current work was to analyse impact salt bath nitriding on behavior tribological characteristics and surface microstructures AISI 316L stainless steels. Nitriding carried out at 580°C for 10 h. tribological, structural before after compared. microstructures, characteristics, as well its hardness, were investigated using optical microscopy (OM), X-ray diffractometer (XRD), profilom...

The microstructure of 8 mm diameter wire produced by the severe deformation of 316L austenitic stainless steel has been examined using TEM and X-ray diffraction. The deformation imparted amounts to a true strain of 6.3. Data from previous studies on strain induced transformation of this steel have been combined with new results to show that true strains .2 are required in order to observe mecha...

In the present research, friction stir welding (FSW) process was used for butt joining of pure copper plate to 316L stainless steel plate. Mechanical properties and microstructural characteristics of the joint were evaluated by microhardness and tensile tests as well as optical and scanning electron microscope (SEM). It was found that microstructure of the weld nugget (WN) has fine grains where...

long–term stability and oxidation resistance of aisi 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. in this study the pack cementation method was employed to coat aisi 439 ferritic stainless steel with manganese. isothermal oxidation was conducted at 800 ºc for 200 hours in static air to investigate the role of coatin...
