Summary
Laser thermal treatment technology is based on the use of heat generated on metal surfaces when absorbing laser beams
Description
This laser quenching technology can be applied for a wide range
of parts. The State Scientific Institution “Physics and Technology Institute
of the Academy of Sciences of Belarus”, for instance, developed a laser
hardening technology for suspension components (brackets, lug) of MAZ 6422 rear
axle to prolong their service life by 3 times. What concerns “shaft-sleeve”
type parts (Borisov plant “Avtohydrousilitel”), the value of operational
necks hardness achieved is 60 HRC units with total part hardness of 40 HRC
units, and etc.
Great prospects are opening for laser quenching in tool-building industry.
Thus, quenching of cutting and cold heading tools, press and stamping
accessories increases their durability by 3-5 times and more. The technology
was tested at BelOMO, “Motovelo”, OJSC, Heavy stamps forging plant, Borisov
plant “Avtohydrousilitel”, and etc. The 1.6–3.0 increase effect was
observed for metal and wood cutting tools, including those with cartridges.
The Institute developed an alloy building process for forging dies involving
5XHM steel, which gives a durability gain by 3-4 times. Laser alloy-building
method provides for obtaining 68-70 HRC units layers on steel and titanium
alloys and 25-30 HRC units layers on aluminium alloys. The method proves to be
efficient with such parts as fodder chopper cutting blades (Production
Association “Gomselmash”), tunneling machine cutters (Production
Association “Belaruskaliy”), and etc.

Technical advantages and economic benefits
This laser treatment method has a number of advantages: improved quenching local properties (which provides for significant saving), no need to use cooling mediums, a possibility to apply this method as a finishing operation due to contraction risk absence, comprehensive prospects for process automation, and etc.
