IPC: C23C8/66
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To form a surface layer, harder than that obtained by ordinary surface hardening, in a short time by irradiating the surface of a coating film with laser beam to melt the coating film and the surface part of the material to be treated and then applying rapid cooling. SOLUTION: As a ferrous metal to be treated, carbon steel, cast iron, cast steel, or alloy steel such as stainless steel is used. For example, a carbon- containing coating agent 2 is applied to the surface of a carbon steel 1 to form a coating film 3, and the coating film 3 and the surface part of the carbon steel 1 are melted by irradiating the surface 4 of the coating film 3 with laser beam 4, followed by rapid cooling. At this time, carbon in the coating agent is allowed to penetrate into the surface part of the material to be treated (carbon steel) and then rapid cooling is carried out, by which a surface layer of martensitic structure containing cementite structure is formed. The coating agent is a coating material prepared by mixing carbonaceous material, binder, surfactant, and water, and its thickness is about 20μm.  By this method, sufficient surface hardness can be obtained independently of the quality of the base material.

Abstract: PROBLEM TO BE SOLVED: To improve the chipping resistance of a block corner part by chamfering or forming a curved surface on at least a part of the block corner part in a bent part in a groove in the transverse direction. SOLUTION: To compatibly provide the wet performance and the uneven wear resistant performance, it is effective to use a S-shaped or Z-shaped block, but since the S-shaped or Z-shaped block has more corner parts in the block, it is disadvantageous for the chipping of the block corner parts caused by the traveling.

Generation of chipping from the corner parts can be prevented, and degradation of the wet performance and the uneven wear resistant performance can be prevented.  Most of the corner parts of the S-shaped or Z-shaped block may be chamfered or formed of a curved surface, but at least two chamfered parts or curved surfaces of the communication groove 4 are effective for the chipping resistance of the block corner parts.
