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 spectros...

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...

aisi 304l austenitic stainless steel with different grain sizes of 0.5 -12 μm was obtained through the martensiticprocess. corrosion behavior of different samples was investigated in a 0.5m hcl solution using open circuitpotential, potentiodynamic polarization and electrochemical impedance spectroscopy tests. also, the correlationbetween the grain size and pitting corrosion resistance was asses...

Zinc electroplating was used to enhance corrosion resistance of porous metal injection molded 440C stainless steel. Controlled porosity achieved by the powder space holder technique and using sodium chloride as a material. The internal pore structure deposited zinc with three different electrolytes acetate, sulfate, chloride. Our results show that all depositions on samples significantly improv...
