the rheological behavior of feedstocks used in powder injection molding technology influences strongly on the final properties of the products. powder loading is one of the important factors that have a great distribution on rheological behaviors. by using the gas atomized spherical 316l stainless steel powder and the binder of 55% paraffin wax+ 40% polyethylen+ 5% stearic acid, four kinds of f...

The enormous demands for metal implant have given rise to a search for cheap material with good bio-tolerability and resistance to corrosion. Although stainless steel has these properties and is widely used for this purpose, its long term application is still a concern. The corrosion resistance of stainless steel depends on the passive layer. Herein, chemical surface treatment, including passiv...

Abstract Metal 3D printing technologies have made it possible to produce different parts, but the mechanical properties of parts connected using not yet been sufficiently studied. In study, 316L stainless steel was laser powder deposited (DED) with cladding head on bed fusion (PBF-LB) printed and joint investigated experimentally. The microstructure examined from cross-sections by optical micro...

Laser drilling and laser engraving are common manufacturing processes that are found in many applications. With the continuous progress of additive manufacturing (3D printing), these processes can now be applied to the materials used in 3D printing. However, there is a lack of knowledge about how these new materials behave when processed or machined. In this study, sheets of 316L stainless stee...

In recent years, stainless steel cladding applications have increased in industrial environments due to this process allows anti-corrosive surfaces be produced from low cost materials, such as carbon steel or low alloy steels. However, to ensure the final quality of the claddings, it is important to know the welding parameters’ effects on the process outputs. This contributes to an appropriate ...

The use of material for implant bearing has a vital role in minimizing failures that endanger recipients. Evaluation contact pressure can be the basis selection and have correlations with wear contribute to need revision operations. current paper aims investigate three different metallic materials, namely cobalt chromium molybdenum (CoCrMo), stainless steel 316L (SS 316L), titanium alloy (Ti6Al...

Abstract The object of the study was 316L steel obtained by method selective laser melting (SLM). structure investigated after different SLM modes. effect modes on second phases precipitation heat treatment studied. It is revealed that fraction precipitates ?-phase correlates with energy density beam during SLM.

In this study, the manufacturability of new types steel-steel composites on an open-architecture laser powder bed fusion (LPBF) system is demonstrated. A hard martensitic stainless tool steel 440C and a soft austenitic 316L are combined in “multi-material” component with discrete continuous material gradients. Interface engineering accomplished through heat treatment to induce phase transformat...
