1. Boriding and boronitrocarburising effects on hardness,wear and corrosion behavior of AISI 4130 steel
ABSTRACT The effects of boriding and boronitrocarburising surface treatments on the microstructure and mechanical properties of AISI 4130 steel have been investigated. Pack boriding was carried out at 1223 K for 5 h and 8 h, while the double treatment of boronitrocarburising consisted of salt bath nitrocarburising at 853 K for 6 h followed by pack boriding a

2. Kinetics of Formation of Fe2B Layers on AISI S1 Steel
In the present work, the AISI S1 steel was pack-borided in the temperature range 1123-1273 K for 2- 8 h to form a compact layer of Fe2B at the material surface. A recent kinetic approach, based on the integral method, was proposed to estimate the boron diffusion coefficients in the Fe2B layers formed on AISI S1 steel in the temperature range 1123-1273 K. In

3. Damage Mechanisms in AISI 304 Borided Steel: Scratch and Daimler-Benz Adhesion Tests
In this study, damage mechanisms in the FeB/Fe2B coatings formed on the surface of AISI 304 steel are determined by adhesion tests. First, the boriding of the AISI 304 steel was carried out through the powder-pack method at 1223 K in the range from 2-10 h of exposure time. After treatment, Berkovich depth-sensing indentation test were conducted; the result s

4. Influência da boretação com pó na resistência ao desgaste, corrosão e oxidação dos aços AISI 1060 e AISI H13 / Influence of pack boriding on the wear, corrosion and oxidation resistance of AISI 1060 and AISI H13 steels
Neste trabalho estudou-se o efeito do tratamento de boretação na resistência ao desgaste, corrosão e oxidação dos aços AISI 1060 e AISI H13. As amostras dos aços foram boretadas com pó a 900 e 1000°C por 2 e 4 horas. Foram realizados ensaios de microdesgaste em máquina do tipo esfera fixa, sem uso de abrasivos, nas amostras boretadas e não boreta
