Description

Изобретение относитс  к области изыскани  легированных чугунов дл  производства вставных седел впускных и выпускных клапанов двигателей внутреннего сгорани .The invention relates to the field of exploration of alloyed cast irons for the production of plug-in seats of intake and exhaust valves of internal combustion engines.

Известен легированный чугун, содержащий углерод, кремний, марганец, хром, никель и железо.Known alloyed iron containing carbon, silicon, manganese, chromium, nickel and iron.

Недостатком известного чугуна  вл етс  низка  износостойкость и коррозионна  стойкость .A disadvantage of the known cast iron is low wear resistance and corrosion resistance.

С целью повышени  изностойкости, коррозионной стойкости и предупреждени  склонности к росту чугуна при температуре до 700° С в состав предложенного чугуна дополнительно ввод т молибден, медь и бор при следующем соотношении компонентов, %:In order to improve iznostoykost, corrosion resistance and prevent the tendency to growth of iron at a temperature of up to 700 ° C, molybdenum, copper and boron are added to the composition of the proposed iron in the following ratio of components,%:

Твердость чугуна после нагрева до 950° С, выдержки 10 час и охлаждении с печью составл ет 37,5-42 HRC.The hardness of the cast iron after heating to 950 ° C, holding for 10 hours and cooling with a furnace is 37.5-42 HRC.

Коррозионные испытани  на двигател х в течение 1500-800 час вставных седел из чугуна показали, что предложенный чугун не подвержен коррозии и обладает высокой износостойкостью .Corrosion tests on engines for 1500-800 hours of plug-in saddles made of cast iron showed that the proposed cast iron does not corrode and has high wear resistance.
