Description
Примен емые сплавы дл стеллитировани клапанов дороги, так как содержат много кобальта.The alloys used for valve steelling are expensive because they contain a lot of cobalt.
Описываемый сплав на железной основе дл стеллитировани клапанов авиамоторов значительно дешевле примен емых и обладает высокой жаропрочностью и износоустойчивостью при высоких температурахДостигнуто это исключением из состава сплава кобальта, замененного железом и никелем, и подбором оптимального соотношени компонентов, вход ш,их в состав сплава.The iron-based alloy described for stellitating the valves of aircraft engines is much cheaper than those used and has high heat resistance and wear resistance at high temperatures. This is achieved by eliminating the cobalt alloy replaced by iron and nickel from the alloy and selecting the optimum ratio of components, entry, and their composition.
Описываемый сплав на железной основе содержит: 25-37% хрома, до 10% никел , 1,3-2,5% углерода, 2,0-4,0% кремни , до 2% марганца; до 10% вольфрама и до 2% ванади .The described iron-based alloy contains: 25-37% chromium, up to 10% nickel, 1.3-2.5% carbon, 2.0-4.0% silicon, up to 2% manganese; up to 10% tungsten and up to 2% vanadium.
Сплав наноситс на поверхность деталей, работаюш,их при высоких температурах, с целью повышени их разгароустойчивости и износоустойчивости при высоких температурах. Наноситс сплав методом наплавлепи ацетиленовой или вольтовой дугой.The alloy is applied to the surface of the parts, working at high temperatures, in order to increase their resistance to wear and durability at high temperatures. The alloy is deposited using a naphlaplep acetylene or volt arc.
Дл механической обработки силава примен ют победитовые резцы или камень.Pointing tools or a stone are used for machining the force.
Твердость сплава в литом виде равна 45-50, а в наплавленном 38- 42 R. Отжиг сплава при температуре около 1100° повышает твердость на 5-12% за счет дисперсионного твердени .The hardness of the alloy in the cast form is equal to 45-50, and in the deposited 38-42 R. Annealing of the alloy at a temperature of about 1100 ° increases the hardness by 5-12% due to dispersion hardening.
Сплав может примен тьс дл жаропрочного лить , изготовлени штампов пуансонов, наплавки на валы машин (например, масл ных насосов и помп), на клапаны, седла авиамоторов, дизелей, паровых машин и т. п.The alloy can be used for heat-resistant casting, making punches, surfacing on machine shafts (e.g., oil pumps and pumps), valves, seat of aircraft engines, diesel engines, steam engines, etc.
Дл стеллитировани клапанов авиамоторов оптимальным вл етс сплав, в котором приведенное содержание компонентов ограничено более узкими пределами, например: 28-34% хрома, 3,0-4,0% никел , 3,5- 4,5% вольфрама, 1,7-2,OVo углерода, 0,5-1,0% марганца, 0,5-1,0% ваннади , 2,5-3,5% кремни , остальное-железо.For stellitating the valves of aircraft engines, an alloy is optimal in which the given component content is limited to narrower limits, for example: 28-34% chromium, 3.0-4.0% nickel, 3.5-4.5% tungsten, 1.7 -2, OVo of carbon, 0.5-1.0% of manganese, 0.5-1.0% of bathdium, 2.5-3.5% of silicon, the rest is iron.
№ 116297- 2 -No. 116297-2 -
Дл седел клапанов, с целью облегчени их обработки резцом, следует примен ть сплав с пониженным до 1,4-1,7% содержанием углерода .For valve seats, in order to facilitate their machining with a chisel, an alloy with a reduced carbon content of 1.4-1.7% should be used.
.Предмет изобретени The subject matter of the invention
Сплав на железной основе дл стеллитировани клапанов авиамоторов , содержащий 25-37% хрома, ,3-2,5% углерода, 2,0-4, кгемни , до 2% марганца, до 2% ваннади и до вольфрама, отличающийс тем, что он дополнительно содержит до 10% никел .Iron-based alloy for stellitating the valves of aircraft engines containing 25-37% chromium, 3-2.5% carbon, 2.0-4, kg, up to 2% manganese, up to 2% bath and up to tungsten, characterized in that it additionally contains up to 10% nickel.
