Laser alloying is an effective method to form functional surface layers (coatings) on metallic materials, particularly stainless steels. Unique phase balance, dislocation substructure, and a possibility obtain gradient microstructures after laser slow down the degradation increase wear resistance. In this work, optimal parameters of their effects microstructure properties were investigated for ...

An advanced simulation process of a stainless steel member in ANSYS technology is described this paper. A three-point bending test hot rolled material grade 1.4301 (AISI 304) has been conducted. The cross-section the beam was IPE80, with span supports equal to 240 mm. results experimental were compared materially and geometrically nonlinear numerical analysis. In order describe behavior materia...

Thick NiTi shape memory alloy coatings (300–500 µm) were produced on graphite and AISI 304 substrates by radio frequency inductively-coupled plasma spray technology (RF-ICP) from feedstock powders. Their microstructure as well chemical phase composition characterized a methodology for the characterization of functional properties thick was developed. The exhibited cubic to monoclinic martensiti...

AISI D6 tool steel and 304 stainless are among the most widely used material in industry. However, this application field can still be expanded through coatings deposition. In regard, objective of work was to evaluate impact by cathodic cage technique using Hastelloy’s cage, on corrosion resistance these steels. Two treatment temperatures were compared. The samples characterized Optical Microsc...

Mechanical properties of machined components are controlled by inducing phase transformations in the outer layer of the materials. Induction hardening is one such manufacturing process where the surface hardness is enhanced while the core is retained with the original structure and characteristics. In this study, a mathematical model had been developed to predict the hardness and the volume fra...
