Abstract
Способ упрочнения седел клапанов двигателя внутреннего сгорания, при котором осуществляют упрочнение поверхности седла клапана в электролите, отличающийся тем, что упрочнение поверхности осуществляют методом микродугового оксидирования в течение 2 ч при силе тока I=0,1÷1 А и напряжении U=400÷600 В, а седло клапана выполнено из алюминиевого сплава.The method of hardening valve seats of an internal combustion engine, in which hardening the surface of the valve seat in an electrolyte is carried out, characterized in that the surface hardening is carried out by microarc oxidation for 2 hours at a current strength of I = 0.1 ÷ 1 A and voltage U = 400 ÷ 600 B, and the valve seat is made of aluminum alloy.
