Abstract:
본 발명에 따른 슬라이딩 피막은 고체 윤활제, 바인더 수지 그리고 저융점 재료를 함유한다. 상기 바인더 수지는 고체 윤활제를 기재(基材)의 표면 위에 유지하기 위한 것으로 유리전이온도를 가진다. 상기 저융점 재료는 상기 바인더 수지의 유리전이온도보다 낮은 융점을 가진다. 상기 저융점 재료는 슬라이딩 부재들 사이에 발생되는 마찰열을 흡수할 수 있는 잠열을 가짐으로 바인더 수지의 열화(劣化)를 지연시킨다. 결과적으로, 상기 슬라이딩 피막은 높은 내눌러붙음성을 만들어낸다.

Abstract:
During the break-in period of track (22) assembly components, galling can occur between the components during use. The components include a pin (68) that is received within a bushing (70) and alternatively a sleeve bearing (74) between the pin (68) and the bushing (70) depending on the load. A method to prevent or reduce galling includes applying a coating (78) of zinc phosphate and a low-friction layer (76) on top of the zinc phosphate (78). The low-friction coating (76) can be made of WS 2 (Tungsten Disulphide), BN (Boron Nitride), MoS 2 (Molybdenum disulfide) or PTFE (Polytetrafluoroethylene) and deposited during a mechanical treatment.
Abstract:
The present invention provides methods and systems for applying a coating to a non-ferrous or ferrous material that includes providing a material, a heat source, an immersion tank, and a drying environment. The material is placed within the heat source and heated to a temperature between the range of between about 204.44°C to about 537.78°C (400°F to about 1000°F). The material is immersed within an immersion containing a ratio of molybdenum disulfide solution to water of between about 2:1 to about 4:1 at a temperature between about 26.67°C to about 48.89°C (about 80°F to 120°F), and the material is dried at a temperature between about 51.67°C to about 98.89°C (125°F and 210°F).
