The article deals with a possibilities of an enhancement functional properties highly stressed components by specific combination surface technology. Two technologies such as plasma nitriding and laser shock peening were selected for the experiment. Those applied upon steel 42CrMo4 frequently utilized in manufacturing strained components. Properties obtained tested following experimental method...

The experimental researches on the promotion of new technologies for local protection metallic parts against plasma nitriding, led to two types special paints in ionic elaborated basis copper lamellar powder combination with magnesium oxide and carbon tetrachloride. In created context, it was considered that could be used not only preventing hardening during nitriding certain technological surf...

AISI 304 stainless steel is a type of austenitic that contains high percentage chromium and nickel. It one the most widely used grades commonly in variety applications, including kitchen equipment, food processing chemical equipment. versatile material due to its excellent corrosion resistance, durability, non-magnetic properties. Low-temperature processes like ion implantation, plasma nitridin...

AISI 304 SS has good corrosion resistance in a variety of environments but does not have to wear. Aggressive marine require materials that can withstand both the biocorrosion and wear associated with impact waves, ocean currents suspended particles. Oxy-nitriding stainless steels be used increase their hardness resistance. The conventional oxy-nitriding process is lengthy, temperature involved ...

Nitriding has long been used to engineer the surfaces of engineering steels improve their surface and subsurface properties. The role compound layer (γ′-Fe4N and/or ε-Fe2-3N) in improving tribological corrosion-resistant properties nitrided established. However, there have very few studies on response tribocorrosion corrosive environments. In this work, behavior a 5 μm thick γ′-Fe4N nitride pro...

In this work, plasma nitriding (PN) and cathode cage deposition (CCPN) treatments were carried out with temperatures of 400 450 °C to evaluate the modifications caused on surface pure niobium samples. XRD, SEM, Vickers microhardness, sphere-disk analyses used characterize coatings’ composition, morphology, hardness, wear resistance. The results showed that treated samples increased hardness res...
