    Based on the analysis of the forces exerted on the ploughshare as the share moves in the ground, the relations of the penetrability of the share to the geometrie factors (such as the angles applied in the mounting of the share, the states of the edge, etc. ) are discussed in the present paper. The principle of ,the self-sharpening of the share edge is presented from the law of abrasion. And the detailed study of the share made of the multilayer materials (for example,by the bead welding or the plasma-spraying) is carried out. From conditions of mechanice and the law of abrasion, a new formula is deduced to obtain the good self-sharpening. This formula indicates the correlations among the factors including the thickness of the layers made of the high abrasion-resisting materials and the bearing materials, the relative coefficients of the abrasion-resistance between layers,and conditions of the ground. Besides, other new formulas are proposed to calculate the relative service life under the conditions of the layers made of the high abrasion-resisting materials on the face or the back of the share.
