The method of forming wear-resistant padding layer and wear-resistant composite material

摘要

A method of forming a wear-resistant padding layer which contains hard particles on a parent metal by supplying the hard particles to a molten pool which is formed on the parent metal by arc generated from an arc electrode. The hard particles are supplied to a molten metal portion, which is being pushed up in the molten pool by the arc, or a molten metal portion which is power flowing in the molten pool. Provided in a wear resistant composite material for scraping earth and rocks is a hard padding layer, which contains the hard particles and is formed on the parent metal to define stripes in an abrading direction of earth and rocks, or are a hard padding layer, which contains the hard particles and is formed on the parent metal, and a soft padding layer formed of a soft material, said hard padding layer and said soft padding layer, respectively, being alternately arranged in an abrading direction of earth and rocks to define stripes in a direction crossing the abrading direction of earth and rocks.
