METHOD FOR MANUFACTURE OF WEAR-RESISTANT PARTS FROM STEEL WITH METASTABLE AUSTENITE STRUCTURE Russian patent published in 1997 - IPC

Abstract RU 2082558 C1

FIELD: powder metallurgy. SUBSTANCE: method involves preparing burden; manufacturing billets with shape close to that of ready part; performing homogenizing annealing, mechanical working and quenching. Burden is completed with 5-12% of hardening powder and 1-1.5% of carbon. Billets are manufactured by pressing. Homogenizing annealing is conducted at temperature of 1,130-1,180 C for 2-4 hours and is combined with copper infiltration. Quenching is effectuated from temperature of 850-1,050 C. EFFECT: simplified method and improved quality by high abrasive resistance. 1 tbl
