Abstract
An abrasion resistant metal earth working surface having a plurality of spaced hollow open ended cup-shaped abrasion resistant studs welded to the surface which collect particulate material in the hollow open ends of the weld studs, wherein the particulate material forms an abrasion resistant barrier limiting abrasion of the earth working surface. The size and shape of the cup-shaped weld studs and the spacing between the array of studs is selected to provide optimum collection of particulate material which reduces wear to extend the efficient operation and life of the earth working surface.
