This technique is cladding the material different from substrate metal on the surface of substrate by infrared ray irradiation. In this study, solid lubricant layers were formed on the surface of stainless steel by infrared rays heating. The layers were formed from the powder mixture of graphite (C) and molybdenum disulfide (MoS2). Infrared ray irradiated with various conditions of current value and irradiation time. The tribological characteristics of solid lubricant layers were evaluated by friction tests. As the result, the good lubricant layer having long wear life were formed from 75vol.%C powder under the condition of the most suitable combination of the current value and the irradiation time. This layer consists of graphite and the MoS2 particles, and MoO3 which are a matrix. The more temperature become high, the more graphite powders attache to the substrate and MoS2 is oxidized. So, the good layer can be formed in suitable heating time and temperature.
