Поверхностные явления в карбидовольфрамовых твердых сплавах, обусловленные импульсным плазменным воздействием

Поверхностные явления в карбидовольфрамовых твердых сплавах, обусловленные импульсным плазменным воздействием

Abstract

Проведено упрочнение твердого сплава путем воздействия на поверхность импульсных плазменных струй, cформированных при электрическом взрыве углеграфитовых волокон. Повышение поверхностной твердости на глубину 20 ÷ 30 мкм происходит за счет смены типа монокарбида вольфрама WC в твердом сплаве на другой тип W2C, который обладает большей твердостью, и уменьшения величины карбида вольфрама W2C в поверхностном слое. Работа выполнена при финансовой поддержке ФЦП «Научные и научно-педагогиче-ские кадры инновационной России» на 2009-2013 гг., государственный контракт П-332.

The hardening of a hard alloy by influence of an impulse plasma jets formed by electric explosion of carbo-graphite fiber on the surface was conducted. The increase of surface hardness 20÷30 µm in depth takes place due to the changing of monocarbide WC in a hard alloy to another type W2C with higher hardness, and size reduction of W2C in a surface layer.
