Introduction to Surface Hardening of Steels

SURFACE HARDENING,a process that includes a wide variety of techniques (Table 1),is used to improve the wear resistance of parts without affecting the more soft,tough interior of the part.This combination of hard surface and resistance to breakage upon impact is useful in partssuchasacamorringgear,bearingsorshafts,International Journal of Surface Science and Engineering It is found that the surface hardness and hardening depth can be improved by using the duplex treatment as compared to only TiN coating.The only coated sample exhibits? Ti?_4 N_2.33,?Ti?_2 N phases,whereas duplex treated samples contain nitrogen-containing martensite phase,iron nitrides,and titanium nitride phases.Instruments - Micro Star 2000 Inc.Metallurgical Micro Star 2000 Inc.established in 1986,became of of Canada's leading Supplier of Metallographic Instruments and Consumables for Metallurgical Sample preparation

Hardenability of Steel Measurement and Factors Metallurgy

A steel transforms from austenite to martensite,if its cooling rate is more than,or equal to the critical cooling rate,the surface hardness then depends principally on the carbon content of the steel,provided,(i) All the carbon was in solution in austenite,resulting in martensite of same carbon content.Friction Stir Processing for Enhancement of Wear Surface coating was characterized by metallography,hardness and pin-on-disc testing.Friction stir processed coating exhibited excellent wear resistance and is attributed to grain boundary pinning and dispersion hardening caused by carbide particles.Enhancement of wear and corrosion resistance of castEnhancement of wear and corrosion resistance of cast A356 aluminium alloy using friction stir processing G.Madhusudhan Reddy 1 and K.Srinivasa Rao 2 1 Defence Metallurgical Research Laboratory,Hyderabad,500 058,India 2 Department of Metallurgical Engineering,A.U.College of Engineering (A),Visakhapatnam,530 003,India.E-mail:arunaraok
