Description
본 발명은 시계, 안경 및 기타의 장식용으로 사용되는 금속소재의 표면처리방법을 개선하여 내식성과 내한성 및 내마모성을 향상시키려는 것이다.The present invention is to improve the corrosion resistance, cold resistance and wear resistance by improving the surface treatment method of the metal material used for watches, glasses and other decorations.
주지된 바와 같이 손목시계나 안경 등과 같이 외관이 중요한 금속재의 장식품 등에는 외관상 장식적인 기능을 갖게하고 아울러 내식성 등을 향상시키기 위하여 도금, 도장, 코팅 등의 표면처리를 하고 있다.As is well known, metal ornaments such as watches and eyeglasses have important surface appearances such as plating, painting, and coating in order to have a decorative function in appearance and to improve corrosion resistance.
그러한 종래의 표면처리 방법 예를 다음에서 차례로 살펴본다.Examples of such conventional surface treatment methods will be described in the following.
안경의 경우는 도 1과 같이 소재의 표면에 Ni도금을 한 후 그 위에 다시 PNP도금이나 혹은 Au도금을 하고 다시 그 위에 전착도장이나 코팅을 하고 있다.In the case of eyeglasses, as shown in Fig. 1, after Ni plating on the surface of the material, PNP plating or Au plating is again applied thereon, followed by electrodeposition coating or coating thereon.
시계의 경우는 도 2와 같이 소재의 표면에 Ni도금을 한 후 그 위에 PNP도금을 하고 그 위에 TiCN 도금과 Au도금을 형성하고 있으며, 또는 도 3과 같이 소재의 표면에 Ni도금을 한 후 그 위에 PNP도금만을 하여 제품을 생산하고 있다.In the case of a watch, as shown in FIG. 2, Ni is plated on the surface of the material, and then PNP plating is formed thereon, and TiCN plating and Au plating are formed thereon, or Ni is plated on the surface of the material as shown in FIG. The product is produced by PNP plating only.
기타의 장식품의 경우는 도 4와 같이 소재의 표면에 Cu도금을 한 후 그 위에 Ni와 Au 도금층을 차례로 형성한 후 그 위에 코팅을 하고있다.In the case of other ornaments, as shown in Figure 4 after the plating of Cu on the surface of the material to form a Ni and Au plating layer thereon and then coated on it.
이러한 종래의 표면처리로는 내식성과 내한성이 부족하여 표면장식에 따르는 수명이 짧을 수 밖에 없고 내식성을 향상시키기 위해 Pd가 함유된 PNP도금을 하고는 있지만 Pd의 가격이 고가이기 때문에 생산원가가 높을 수밖에 없으며, PNP와 아울러 TiCN도금을 하더라도 내식성과 내한성 및 내마모성 등 모든 조건을 골고루 높이는 데는 한계가 있는 것이다.The conventional surface treatment is insufficient in corrosion resistance and cold resistance, so the service life of the surface decoration is shortened and PNP plating containing Pd is used to improve the corrosion resistance, but the production cost is high due to the high price of Pd. In addition, even with PNP and TiCN plating, there is a limit to evenly raising all conditions such as corrosion resistance, cold resistance and abrasion resistance.
상기 문제점을 충분히 감안하여 안출한 본 발명은 장식용 금속재 소재의 표면처리 방법을 개량하여 생산원가를 줄이면서도 내식성과 내한성 및 내마모성 등의 모든 조건을 크게 향상시켜 뛰어난 품질을 가지면서 수명이 매우 긴 제품을 제공할 수 있게 함을 목적으로 하는 것이다.The present invention devised in view of the above problems sufficiently improves the surface treatment method of the decorative metal material, while greatly reducing all the production costs, such as corrosion resistance, cold resistance and wear resistance, and has a very long life products with excellent quality. The purpose is to make it available.
