Abstract

The present invention relates to a method for coating a stainless steel material with a metal compound such as nickel, cobalt, alumina, titanium, or titanium oxide, and a coated stainless steel product obtained by the method. That is, after cleaning and drying the stainless steel material, temperature in a chamber is maintained at 200 to 250℃ by using one or more types of gas mixtures selected from a group consisting of oxygen, acetylene gas, argon, nitrogen, and the like. Moreover, plasma etching is performed while pressure is maintained at 1 × 10 - 4 to 8 × 10 - 6 torr to form etching on a surface of an object to be coated, which is the stainless steel material, and after placing the object to be coated on a jig, the object to be coated is coated by a conventional metal deposition method.

발생하는 각종 물질을 제거하는 일종의 템퍼링 공정을 거친 후, 이를 엣칭 챔버에 넣고, 엣칭 챔버를 감압하에서 필라멘트가 연결된 전극에 전류를 인가하고, 산소 가스, 질소 가스, 아세틸렌 가스, 아르곤 가스로 이루어진 군에서 선택된 1종 또는 2종을 필라멘트에 통과시켜 플라스마를 형성시켜 스테인레스 스틸 재료의 표면을 엣칭하고, 이를 치구에 조립하고, 알루미나, 산화티타늄, 티타늄, 닉켈 등의 금속을 이용하는 통상의 증착 방법으로 코팅함으로서 스테인레스 스틸의 표면에 내구성이 우수한 코팅을 행할 수 있음을 발견하고, 본 발명을 완성하게 되었다.After undergoing a kind of tempering process to remove various substances that are generated, it is placed in an etching chamber, and a current is applied to the electrode to which the filament is connected under reduced pressure in the etching chamber, and from the group consisting of oxygen gas, nitrogen gas, acetylene gas, and argon gas. By passing the selected one or two types through the filament to form a plasma, etching the surface of the stainless steel material, assembling it to a jig, and coating it by a conventional deposition method using metals such as alumina, titanium oxide, titanium, nickel, etc. It has been discovered that a coating with excellent durability can be applied to the surface of stainless steel, and the present invention has been completed.

최근, 가전 제품, 휴대폰, 엠피3 등 각종 제품에 부품으로서 각종 스테인레스 스틸 재료가 사용되나, 이들 스테인레스 스틸재료에 원하는 컬러로 코팅할 수 없어 제품의 가치를 떨어뜨리거나, 또는 제품의 만족도를 저하시켜 이를 해결할 수 없었다Recently, various stainless steel materials are used as parts for various products such as home appliances, mobile phones, MP3, etc., but these stainless steel materials cannot be coated in a desired color, thereby reducing the value of the product or lowering the satisfaction of the product. couldn't solve this

이상에서와 같이, 본 발명에 따른 스테인레스 스틸 재료 표면의 엣칭방법에 의해 얻어진 엣칭된 스테인레스 스틸 재료는 멀티 코팅이 용이하며, 이에 따라 각종 색상의 코팅을 원하는 대로 얻을 수 있으며, 본 발명은 종래 스테인레스 스틸상에As described above, the etched stainless steel material obtained by the method for etching the surface of the stainless steel material according to the present invention can be easily multi-coated, and thus various colors of coating can be obtained as desired. on top

금속 증착 코팅 할 수 없다는 개념을 바꿔 각종 스테인레스 스틸 재료의 표면을 코팅하여 벗겨지지 않으며, 변색되지 않는 색상을 제공하는 유용한 기술이다.It is a useful technology that provides a color that does not peel off and does not discolor by coating the surface of various stainless steel materials by changing the concept that metal deposition cannot be coated.
