Tapered roller bearings have tapered rolling elements and rings. This increases the surface contact area between the inner and outer rings, allowing for large radial and thrust loads compared to ball or cylindrical bearings. While there are many steels used for the production of bearings, the most commonly used bearing material is AISI 52100.
Laser Heat Treating Capabilities Preco, Inc.For example, laser casehardening of transformation hardening metals provides high wear and abrasion resistance with minimum distortion. In addition, laser spot annealing of precipitation and work hardened metals (i.e., 300 series stainless steel and copper alloys) restores ductility and improves formability and fatigue resistance in critical areas.
Laser Materials Processing for Industrial Applications Jul 18, 2018 · Some of the recently developed industrial applications such as laser micro texturing of automotive components, laser deposition based repair of pressure die casting dies, laser brazing of aluminium alloys to steel, laser hardening of bearing steels and laser metal
Surface hardening with discrete laser spot treatment is an interesting solution since the adoption of a single pulse allows the treatment of different surface geometries avoiding the effect of back tempering. The aim of this work is to find a suitable process window in which operate to get best results in terms of hardness, diameter and depth of the treated region.
Laser surface hardening of austempered (bainitic) ball May 01, 2007 · Laser surface hardening (LSH) is a directed energy beam assisted surface engineering technique that allows controlled heating followed by self-quenching of steel components, leading to surface hardening (martensitic transformation) up to a limited depth without affecting the bulk , . In the present study, an attempt has been made to enhance surface hardness and wear resistance of
Laser surface hardening of bearing steels DR-NTULaser surface hardening has emerged as a promising technique to improve the wear resistance of machine components such as bearings, gears and camshafts. However, a lack of thorough understanding of the underlying mechanism coupled with the stringent requirements on surface properties still hinders its widespread application in industries.
Water can act as an effective cooling agent during processing of materials. This can be beneficial especially for surface hardening of steels whereby a rapid quenching rate is desired to generate a
Niroj Maharjan - Development Scientist - A*STAR - Agency In this study, the underwater laser hardening of bearing steels is experimentally investigated using a fiber laser. The study found that underwater laser hardening increases surface hardness by about 3.5 times than that of the base material which is higher than in Water can act as an effective cooling agent during processing of materials.Laser hardening of AISI 52100 bearing steel with a Laser hardening of AISI 52100 bearing steel with a discrete fiber laser spot.
