METHOD OF SURFACES RECONDITIONING OF ROTATION BODIES Russian patent published in 2018 - IPC B23K9/04 B23P6/02 

FIELD: technological processes.

SUBSTANCE: invention can be used for invention relates to worn-out surfaces buildup reconditioning of rotation body. Electric arc surfacing of the first layer of wear-resistant material is carried out along a helical line in a back-step manner. Surfacing of the remaining layers is carried out transversely by the oscillating electrode. After heat treatment, build up surface is machined using friction geomodifiers. As geomodifiers of friction, lubricated powders are used, including serpentinites and/or schungites. When surfacing layers transversely with an oscillating electrode, high frequency ultrasonic oscillations with a frequency of at least 15 kHz may be applied to the oscillations of the electrode. Ultrasonic effect can be carried out during the cooling of the body during its heat treatment. Heating of the body is carried out preliminary and/or concomitant. Associated heating is started from the side opposite to the surfacing, and the source of concomitant heating is moved in the direction of surfacing.

EFFECT: use of the invention prevents distortion of the dimensions and shape of the build up part, prevents the appearance of cracks in the surfacing, reduces the size of the allowances for machining.
