·Ion-plasma nitriding is widely used to improve the service properties of steel [].The structure of the surface layers and the depth of the nitrided layer depend to a large extent on the state of the surface,the elemental composition of steel,and the nitriding regime [24].The effect of the temperature of the nitriding regime can be explained by the strong dependence of the diffusion rate results for this questionHow does chromium plating affect the mechanical properties?How does chromium plating affect the mechanical properties?Chromium plating is used widely in industry to enhance wear,abrasion resistance and to restore the dimensions of undersized parts.However,tensile residual stress always exists in chrome layer because of hydrogen embrittlement so it affect to mechanical properties of the chromium plating machine element,especially in fatigue strength.Effect of Residual Stress and Microcracks in Chrome results for this questionHow does nitriding improve the corrosion resistance of steel?How does nitriding improve the corrosion resistance of steel?Nitriding,one of the most important and common surface modification processes,can improve the surface corrosion resistance of steel parts along with increasing wear and fatigue resistance.Nitriding for Corrosion and Wear Fatigue Resistance

results for this questionHow does the temperature affect the efficiency of nitriding?How does the temperature affect the efficiency of nitriding?Since nitrogen ions are made available by ionization,differently from gas or salt bath,plasma nitriding efficiency does not depend on the temperature.Plasma nitriding can thus be performed in a broad temperature range,from 260°C to more than 600°C.Nitriding Metallurgy for DummiesConventional plasma nitriding produces two simultaneously reverse effects on hard chromium electroplated coatings.(i) A high temperature condition relieves internal stresses of the electroplated layercaused by formation of intermediate unstable chromium hydrides.Author:Shayan Hossein Sarraf,Mansour Soltanieh,Hossein AghajaniCited by:21Publish Year:2016Repairing the cracks network of hard chromium

Was this helpful?People also askWhat is the reactivity of plasma nitriding media?What is the reactivity of plasma nitriding media?In plasma nitriding,the reactivity of the nitriding media is not due to the temperature but to the gas ionized state.In this technique intense electric fields are used to generate ionized molecules of the gas around the surface to be nitrided.Nitriding Metallurgy for DummiesEffect of Residual Stress and Microcracks in Chrome Chromium plating is used widely in industry to enhance wear,abrasion resistance and to restore the dimensions of undersized parts.However,tensile residual stress always exists in chrome layer because of hydrogen embrittlement so it affect to mechanical properties of the chromium plating machine element,especially in fatigue strength.In this paper,effect of residual stress in chrome
