본 발명은 해초형 나노튜브를 구비한 저마찰 부재에 관한 것으로, 모재 표면에서 해초와 같이 돌출된 나노튜브가 피접동부재의 이동방향으로 쏠리면서 액체 윤활제의 유동성을 향상시켜줌으로써 표면마찰을 효과적으로 줄일 수 있도록 한 것이다. 이러한 본 발명은, 피접동부재의 표면접촉으로 일어나는 마찰을 줄일 수 있도록 표면에 다수의 딤플이 형성된 모재와; 상기 딤플 내부에 충진된 고착재와; 상기 고착재에 매립되고 상기 고착재에 대한 표면처리에 의해 외측으로 돌출된 나노 튜브와; 상기 모재 표면에 도포된 액체 윤활제를 구비하여, 상기 돌출된 나노튜브가 상기 피접동부재의 이동방향으로 쏠리면서 상기 액체 윤활제의 유동성을 향상시켜줌으로써 표면마찰을 줄일 수 있도록 한 것을 특징으로 한다.
Abstract:
La presente patente trata de un aceite lubricante adicionado con nano partículas de grafeno decorado, el cual es llamado nanolubricante. Este nanolubricante tiene aplicaciones automotrices e industriales y ofrece como principales beneficios mejoras simultaneas en las propiedades térmicas, Teológicas y tribológicas del lubricante usado como fluido base. Adicionalmente, este nanolubricante ofrece un comportamiento reopéctico a partir de una concentración específica, mismo comportamiento que le confiere la capacidad de incrementar su viscosidad a través del tiempo mientras esté sometido a una tasa de corte constante. Por último, el grafeno decorado puede incluir nanopartículas metálicas, cerámicas o poliméricas, puede estar en un rango de concentración de 0.5 % peso/peso hasta 2% peso/peso sin que el lubricante base cambie su comportamiento de fluido newtoniano, mientras que para concentraciones mayores a 2% peso/peso y hasta 3% peso/peso se observará el comportamiento reopéctico antes mencionado.

Abstract:
The invention relates to a friction-reducing polymer material with dry-running capability, comprising a polymer matrix material and fillers, where the fillers comprise reinforcing particles, particles of high-hardness materials and lubricant particles. The invention further relates to a mechanical end-face seal comprising a rotating friction-reducing ring and a stationary counter-ring, where the friction-reducing ring and/or the counter-ring comprises the friction-reducing polymer material with dry-running capability. The invention further relates to the use of these polymer materials with dry-running capability for dry-running applications, more particularly as material for displacement elements in wet- and dry-running pumps.
Abstract:
A nanolubricant composition is described where the lubricant composition includes a flowable oil or grease with a multi-component nanoparticle dispersed in the flowable oil or grease. The multi-component nanoparticle includes a first nanoparticle component which effects thermal conductivity at a part interface and a second nanoparticle component which effects shearing at a part interface.
Abstract:
The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.
Abstract:
A threaded joint for steel pipes comprises a pin (1) and a box (2) each having a threaded portion (3a or 3b) and an unthreaded metal-to-metal contact portion (4a or 4b) as contact surfaces which contact each other when the joint is fastened. The contact surfaces (3a and 4a and/or 3b and 4b) of at least one of the pin (1) and the box (2) are coated with a lower layer of a solid lubricating coating containing a solid lubricating powder (e.g., molybdenum disulfide, tungsten disulfide, or graphite) and a binder (e.g., an epoxy or other organic resin) and an upper layer of a solid corrosion protective coating formed by an organic resin which does not contain solid particles.
