The present invention relates to a relief valve for an oil pump with an extended service life, and to a surface treatment method for the same. To be more specifically, the present invention relates to a relief valve for an oil pump with an extended service life, and a surface treatment method for the same, which form an electroless nickel plating layer and Teflon coating on an external surface of a relief valve installed in the oil pump in order to reduce surface scratches and wear phenomena of the relief valve, thereby ensuring pleasant driving through smooth steering and reduced abnormal noises of a steering device. In addition, the relief valve installed in the oil pump of the steering device includes the electroless nickel plating layer and Teflon coating consecutively formed on the external surface thereof in order to deal with friction generated by instantly applied pressure during left and right steering of the steering device.

    본 발명은 사용수명이 연장된 오일펌프용 릴리프 밸브 및 이의 표면처리방법에 관한 것으로, 보다 상세하게는 오일펌프에 설치되는 릴리프 밸브의 외표면에 무전해 니켈 도금층 및 테프론 코팅을 형성하여 릴리프 밸브의 표면 스크래치 및 마모현상을 감소시킴으로써 조향장치의 원활한 조향 및 이음발생의 저감을 통해 쾌적한 운전을 보장할 수 있도록 하는 사용수명이 연장된 오일펌프용 릴리프 밸브 및 이의 표면처리방법에 관한 것이다. 본 발명은 조향장치의 오일펌프에 설치되는 릴리프 밸브에 있어서, 상기 릴리프 밸브의 외표면에는 무전해 니켈 도금층 및 테프론 코팅층이 순차적으로 형성되어 조향장치의 좌우 조향시 순간 가압에 의해 발생되는 마찰에 대응할 수 있도록 구성되는 것을 특징으로 한다.
