Description

금속 및 세라믹 복합재 형성 방법{METHOD OF FORMING A COMPOSITE INCLUDING METAL AND CERAMIC}Method of forming metal and ceramic composites {METHOD OF FORMING A COMPOSITE INCLUDING METAL AND CERAMIC}

본 발명은 금속 및 세라믹 복합재 형성 방법에 관한 것이다.The present invention relates to methods of forming metal and ceramic composites.

일반적으로 저온 스프레이 장치는 마이크로미터(㎛) 크기의 분말 입자를 질소, 헬륨, 공기 등의 고압 가스를 이용하여 입자 속도를 가속시키면 모재와 코팅 소재에 따른 임계 속도에 다다르면서 코팅이 시작되는 저온 분사 코팅(cold spray coating) 장치를 의미한다.In general, a low-temperature spray device accelerates particle speed by using high-pressure gas such as nitrogen, helium, or air to micrometer (㎛)-sized powder particles, and the low-temperature spray starts coating as the critical speed is reached according to the base material and coating material. Means a cold spray coating device.

하지만, 저온 분사 코팅에 사용되는 소재 중 경도가 높은 세라믹 또는 경도가 높은 금속 소재는 저온 분사 코팅에 부적합하고 적층 효율이 떨어지며, 코팅층 특성이 저하될 수 있다.However, ceramic materials with high hardness or metal materials with high hardness among materials used for low-temperature spray coating are unsuitable for low-temperature spray coating, have poor lamination efficiency, and may deteriorate coating layer properties.

이러한 문제점을 보완하기 위해 금속과 세라믹 분말을 혼합하여 저온 분사 코팅을 수행하지만, 금속과 세라믹 분말의 밀도 차이에 의해 균일한 코팅층을 얻기 어렵고, 접합 강도가 약한 문제점이 있다.In order to compensate for this problem, low-temperature spray coating is performed by mixing metal and ceramic powder, but it is difficult to obtain a uniform coating layer due to the difference in density between the metal and ceramic powder, and the bonding strength is weak.

본 발명이 해결하고자 하는 기술적 과제는 적층 효율이 우수하고 균일하며, 고인성(toughness), 고내식성(corrosion resistance), 내마모성(wear resistance) 및 내열성(hear resistance)이 개선된 금속 및 세라믹 복합재의 형성 방법을 제공하고자 한다.The technical problem to be solved by the present invention is to form a metal and ceramic composite having excellent and uniform lamination efficiency and improved toughness, high corrosion resistance, wear resistance and heat resistance. We want to provide a way.

Coating is performed, the ceramic powder is coated through a thermal spraying process, and the metal powder and the ceramic powder are coated simultaneously.

상기 세라믹 분말은 알루미나, 실리콘 카바이드, 텅스텐 카바이드 및 다이아몬드 중 적어도 어느 하나 이상일 수 있다.The ceramic powder may be at least one of alumina, silicon carbide, tungsten carbide, and diamond.

상기 세라믹 분말의 입경은 5~ 200㎛일 수 있다.The particle diameter of the ceramic powder may be 5 to 200 μm.

상기 열용사 공정은 가스 화염 용사법, 저속 및 고속 화염 용사법, 폭발 용사법, 대기 플라즈마 용사법 및 감압 플라즈마 용사법 중에서 선택된 어느 하나일 수 있다.The thermal spraying process may be any one selected from a gas flame spraying method, a low-speed and high-speed flame spraying method, an explosive spraying method, an atmospheric plasma spraying method, and a reduced-pressure plasma spraying method.

상기 저온 분사 공정은 저온 분사 노즐을 통해 수행하고, 상기 열용사 공정은 상기 저온 분사 노즐과 별도의 열용사 노즐을 통해 수행할 수 있다.The low-temperature spraying process may be performed through a low-temperature spray nozzle, and the thermal spraying process may be performed through a thermal spray nozzle separate from the low-temperature spray nozzle.

또한, 본 발명의 다른 구현예는, 기판, 금속 분말 및 세라믹 분말을 준비하는 단계, 및 상기 금속 분말 및 상기 세라믹 분말을 분사하여 상기 기판을 코팅하는 단계를 포함하며, 상기 금속 분말은 제1 금속 분말 및 상기 제1 금속 분말보다 상대적으로 경도가 높은 제2 금속 분말을 포함하고, 상기 제1 금속 분말은 저온 분사 공정을 통해 코팅을 수행하고, 상기 제2 금속 분말 및 상기 세라믹 분말은 열용사 공정을 통해 코팅을 수행하며, 상기 금속 분말 및 상기 세라믹 분말의 코팅은 동시에 수행되는 금속 및 세라믹 복합재 형성 방법을 제공한다.Further, another embodiment of the present invention includes preparing a substrate, metal powder, and ceramic powder, and coating the substrate by spraying the metal powder and the ceramic powder, wherein the metal powder is a first metal powder and a second metal powder having a relatively higher hardness than the first metal powder, wherein the first metal powder is coated through a low-temperature spraying process, and the second metal powder and the ceramic powder are subjected to a thermal spraying process The coating is performed through, and the coating of the metal powder and the ceramic powder is performed simultaneously.

이하, 본 발명의 구현예를 상세히 설명하기로 한다. 다만, 이는 예시로서 제시되는 것으로, 이에 의해 본 발명이 제한되지는 않으며 본 발명은 후술할 청구항의 범주에 의해 정의될 뿐이다.Hereinafter, embodiments of the present invention will be described in detail. However, this is presented as an example, and the present invention is not limited thereby, and the present invention is only defined by the scope of the claims to be described later.

명세서 전체에서, 어떤 부분이 어떤 구성요소를 “포함”한다고 할 때, 이는 특별히 반대되는 기재가 없는 한 다른 구성요소를 제외하는 것이 아니라 다른 구성요소를 더 포함할 수 있는 것을 의미한다.Throughout the specification, when a certain component is said to "include", it means that it may further include other components without excluding other components unless otherwise stated.

먼저, 도 1을 참고하여 본 발명의 일 실시예에 따른 금속 및 세라믹 분말 복합재의 코팅 장치 및 형성 방법에 대해서 상세하게 설명한다.First, with reference to FIG. 1, a coating apparatus and a method for forming a metal and ceramic powder composite material according to an embodiment of the present invention will be described in detail.

도 1은 본 발명의 일 실시예에 따른 코팅 장치의 개략도이다.1 is a schematic diagram of a coating apparatus according to an embodiment of the present invention.

도 1을 참고하면, 본 발명의 일 실시예에 따른 코팅 장치는 기판(10), 기판(10) 위에 금속/ 세라믹 분말 복합재(10)를 형성하기 위한 저온 분사 노즐(30A) 및 열용사 노즐(30B)을 포함한다.Referring to FIG. 1 , the coating apparatus according to an embodiment of the present invention includes a substrate 10, a low-temperature spray nozzle 30A and a thermal spray nozzle for forming a metal/ceramic powder composite 10 on the substrate 10 ( 30B).

금속 분말은 순수 금속, 혼합 금속 또는 합금일 수 있고, 예를 들어 알루미늄, 구리, 주석, 철 및 코발트 중 적어도 어느 하나 이상일 수 있으나, 이에 한정되는 것은 아니며, 다양한 금속 재료일 수 있다.The metal powder may be a pure metal, a mixed metal, or an alloy, and may be, for example, at least one of aluminum, copper, tin, iron, and cobalt, but is not limited thereto, and may be various metal materials.

금속 분말의 입경은 5~ 200㎛일 수 있다. The particle size of the metal powder may be 5 μm to 200 μm.

금속 분말의 입경이 5㎛ 미만일 경우 금속 분말의 송급(loading)이 불균일할 뿐만 아니라, 코팅 공정을 수행할 때 날리는 현상이 발생할 수 있어 코팅 공정에서 적층이 용이하지 않을 수 있고, 금속 분말의 입경이 200㎛ 초과일 경우에는 금속 분말이 완전히 용융되지 않아 코팅 공정이 용이하지 않을 수 있기 때문이다.When the particle diameter of the metal powder is less than 5 μm, not only the loading of the metal powder is non-uniform, but also a flying phenomenon may occur during the coating process, which may make it difficult to stack in the coating process, and the particle diameter of the metal powder This is because when the thickness exceeds 200 μm, the coating process may not be easy because the metal powder is not completely melted.

여기서, 금속 분말은 상대적으로 경도가 낮은(soft) 제1 금속 분말과 제1 금속 분말 대비 경도가 높은(hard) 제2 금속 분말을 포함할 수 있다.Here, the metal powder may include a first metal powder having a relatively low hardness (soft) and a second metal powder having a relatively high hardness (hard) compared to the first metal powder.

또한, 세라믹 분말은 알루미나, 실리콘 카바이드, 텅스텐 카바이드 및 다이아몬드 중 적어도 어느 하나 이상일 수 있으나, 이에 한정되는 것은 아니다.In addition, the ceramic powder may be at least one of alumina, silicon carbide, tungsten carbide, and diamond, but is not limited thereto.

세라믹 분말의 입경은 5~ 200㎛일 수 있다.The particle diameter of the ceramic powder may be 5 to 200 μm.

이는 세라믹 분말의 입경이 5㎛ 미만일 경우 세라믹 분말의 송급(loading)이 불균일할 뿐만 아니라, 코팅 공정을 수행할 때 날리는 현상이 발생할 수 있어 코팅 공정에서 적층이 용이하지 않을 수 있고, 세라믹 분말의 입경이 200㎛ 초과일 경우에는 세라믹 분말이 완전히 용융되지 않아 코팅 공정이 용이하지 않을 수 있기 때문이다.This is because when the particle size of the ceramic powder is less than 5 μm, the loading of the ceramic powder is not uniform, and a flying phenomenon may occur during the coating process, which may make it difficult to stack in the coating process, and the particle size of the ceramic powder This is because when the thickness exceeds 200 μm, the coating process may not be easy because the ceramic powder is not completely melted.

본 실시예에 따른 코팅 장치의 저온 분사 노즐(30A) 및 열용사 노즐(30B)은 기판(20)의 전면에서 자유롭게 이동할 수 있으며, 기판(20)으로부터 소정 거리 이격되어 위치한다.The low-temperature spraying nozzle 30A and the thermal spraying nozzle 30B of the coating apparatus according to the present embodiment can move freely on the front surface of the substrate 20 and are spaced apart from the substrate 20 by a predetermined distance.

또한, 저온 분사 노즐(30A) 및 열용사 노즐(30B)은 기판(20) 의 일면에서 소정 거리 이격되어 위치한 채로 동시에 동일한 위치로 이동할 수 있으며, 기판(20)의 코팅을 위한 금속 분말 및/ 또는 세라믹 분말을 가스와 함께 혼합 분사할 수 있다.In addition, the low-temperature spraying nozzle 30A and the thermal spraying nozzle 30B may move to the same position at the same time while being spaced apart from one surface of the substrate 20 by a predetermined distance, and the metal powder for coating the substrate 20 and/or Ceramic powder can be mixed and sprayed together with gas.

저온 분사 노즐(30A)을 통해 저온 분사 공정을 수행할 수 있으며, 저온 분사 공정은 고상 상태의 공정으로서 금속의 소성 변형을 통하여 코팅이 이루어진다. A low temperature spraying process may be performed through the low temperature spraying nozzle 30A, and the low temperature spraying process is a solid state process and coating is performed through plastic deformation of metal.

이러한 저온 분사 공정은 수십 mm의 상대적으로 두꺼운 코팅이 가능하며, 소재의 상변화나 산화가 일어나지 않아 원래 분말의 특징을 그대로 유지할 수 있다는 장점이 있다. This low-temperature spraying process is advantageous in that a relatively thick coating of several tens of mm is possible, and the characteristics of the original powder can be maintained without phase change or oxidation of the material.

본 실시예에 따른 저온 분사 노즐(30A)에서는 기판(20)의 일면에 금속 분말의 코팅을 수행할 수 있다.In the low-temperature spray nozzle 30A according to the present embodiment, one surface of the substrate 20 may be coated with metal powder.

열용사 노즐(30B)을 통해서는 열용사 공정을 수행할 수 있으며, 열용사 코팅은 일반적으로 고온의 플라즈마 불꽃에 금속 및/ 또는 세라믹 분말을 주입하여 가열한 후 완전 용융 또는 반용융된 상태에서 기판(20)의 표면에 적층하여 피막을 형성하는 방법이다.A thermal spraying process can be performed through the thermal spraying nozzle 30B. In general, thermal spraying coating is performed by injecting metal and/or ceramic powder into a high-temperature plasma flame and heating the substrate in a completely melted or semi-melted state. It is a method of forming a film by laminating on the surface of (20).

열용사 공정으로는 가스 화염 용사법, 저속 및 고속 화염 용사법, 폭발 용사법, 대기 플라즈마 용사법, 감압 플라즈마 용사법 등이 포함될 수 있으나, 이에 한정되지 않는다.The thermal spraying process may include, but is not limited to, a gas flame spraying method, a low-speed and high-speed flame spraying method, an explosive spraying method, an atmospheric plasma spraying method, a reduced-pressure plasma spraying method, and the like.

본 실시예에 따른 열용사 노즐(30B)에서는 기판(20)의 일면에 세라믹 분말의 코팅을 수행할 수 있다.In the thermal spraying nozzle 30B according to the present embodiment, one surface of the substrate 20 may be coated with ceramic powder.

또한, 금속 분말이 상대적으로 경도가 낮은(soft) 제1 금속 분말과 제1 금속 분말 대비 경도가 높은(hard) 제2 금속 분말을 포함할 경우에는 상대적으로 경도가 낮은 제1 금속 분말은 저온 분사 노즐(30A)을 통해 분사되며, 상대적으로 경도가 높은 제2 금속 분말은 열용사 노즐(30B)을 통해 세라믹 분말과 함께 분사될 수 있다.In addition, when the metal powder includes a first metal powder having a relatively low hardness (soft) and a second metal powder having a relatively high hardness (hard) compared to the first metal powder, the first metal powder having a relatively low hardness is sprayed at low temperature The second metal powder, which is sprayed through the nozzle 30A and has a relatively high hardness, may be sprayed together with the ceramic powder through the thermal spraying nozzle 30B.

즉, 본 실시예에 따른 금속 및 세라믹 복합재(10) 형성 방법은 저온 분사 노즐(30A) 및 열용사 노즐(30B)을 함께 포함하고 있는 코팅 장치를 사용함으로써, 저온 분사 공정과 열용사 공정이 동시에 수행될 수 있다.That is, in the method of forming the metal and ceramic composite 10 according to the present embodiment, the low-temperature spraying process and the thermal spraying process are performed simultaneously by using a coating apparatus including the low-temperature spraying nozzle 30A and the thermal spraying nozzle 30B. can be performed

일반적으로 세라믹 분말 또는 상대적으로 경도가 높은 금속 분말의 경우 저온 분사 공정을 통해 복합재(10)를 형성할 경우 적층 효율이 떨어지고 코팅층 특성이 저하될 뿐만 아니라, 기판(20)과의 접합 강도도 상대적으로 떨어질 수 있다. In general, in the case of ceramic powder or metal powder having relatively high hardness, when the composite material 10 is formed through a low-temperature spraying process, not only the lamination efficiency decreases and the coating layer characteristics deteriorate, but also the bonding strength with the substrate 20 is relatively low. can fall

이에 본 실시예에 따른 복합재(10) 형성 방법은 세라믹 분말 및 경도가 높은 제2금속 분말은 열용사 노즐(30B)을 이용한 열용사 공정을 수행하고, 이와 동시에 상대적으로 경도가 낮은 제2 금속 분말은 저온 분사 노즐(30A)을 이용한 저온 분사 공정을 수행하여 적층 효율이 우수하고 코팅층의 특성을 개선시킬 뿐만 아니라, 기판(20)과의 접합 강도도 개선할 수 있다.Therefore, in the method of forming the composite material 10 according to the present embodiment, the ceramic powder and the second metal powder having high hardness are subjected to a thermal spraying process using the thermal spraying nozzle 30B, and at the same time, the second metal powder having a relatively low hardness By performing the low-temperature spraying process using the silver low-temperature spray nozzle 30A, stacking efficiency is excellent, characteristics of the coating layer can be improved, and bonding strength with the substrate 20 can be improved.

이렇게, 본 발명의 실시예에 따른 복합재의 형성 방법에 따라 형성된 금속 및 세라믹 복합재를 촬영한 사진을 도 2에 나타내었다.In this way, a photograph of a metal and ceramic composite formed according to the method for forming a composite according to an embodiment of the present invention is shown in FIG. 2 .

도 2를 참고하면 금속과 세라믹 복합재가 기판 상에서 균일하게 형성되어 있는 것을 확인할 수 있었다.Referring to FIG. 2 , it was confirmed that the metal and ceramic composite material was uniformly formed on the substrate.

이상과 같이 본 발명의 일 실시예에 따른 금속 및 세라믹 복합재 형성 방법에 따르면, 저온 분사 코팅과 열용사 코팅을 함께 수행하여 복합재를 형성함으로써, 적층 효율이 우수하고 균일하며, 고인성, 고내식성, 내마모성 및 내열성이 개선될 수 있는 장점이 있다.As described above, according to the method for forming a metal and ceramic composite according to an embodiment of the present invention, by performing low-temperature spray coating and thermal spray coating together to form a composite, the lamination efficiency is excellent and uniform, high toughness, high corrosion resistance, There is an advantage that wear resistance and heat resistance can be improved.
