【摘要】H13 die steel was implanted with tungsten using a matal vapour vacuum arc (MEVVA)ion source.When the pulsed beam current density of tungsten ions increased to 6m A_cm-2,some voids appeared in the high voltage electron microscope(HVEM)micrograph, which would disappear at and annealing temperature of 600℃.HVEM and x-ray diffraction were used for observing the phase structure of the annealed

and

un-annealed

H13

steel

after

the

steel

was

Implanted.Results of wear and hardness tests Indicated that whether the voids appear significantly Influences the hardness and wear of H13 steel.Reasons for the formation of voids and the relation between the surface mechanical property and voids are discussed In terms of collision theory.
