Sliding surface of sliding member

A sliding surface of a sliding member directly hardened in a linear or dotted shape to form projected parts (3a) and to form recessed parts (3b) at non-directly hardened portions adjacent to the directly hardened portions thereof so that recessed and projected surfaces can be formed on the sliding s...

Beschreibung
Zusammenfassung:	A sliding surface of a sliding member directly hardened in a linear or dotted shape to form projected parts (3a) and to form recessed parts (3b) at non-directly hardened portions adjacent to the directly hardened portions thereof so that recessed and projected surfaces can be formed on the sliding surface by the directly hardened portions and non-directly hardened portions. The directly hardened portions may be formed in a lattice-shape, parallel linear shape, concentrical shape, or spiral shape. Since the recessed and projected surfaces are formed on the sliding surface by the directly hardened portions and the non-directly hardened portions, the anti-seizure property thereof can be improved.
