무전해 니켈-인 코팅은 높은 마모 저항성, 높은 부식 저항성, 높은 경도와 견고성, 우수한 윤활성 등의 고유한 특성 때문에 많은 산업 분야에서 널리 사용되고 있습니다. Ni-P 매트릭스 내에서 나노 크기 입자를 보강 단계로 결합하여 무전해 코드 위치 공정을 통해 기능성 나노미터 복합체 코팅이 생성됩니다. Ni-P 코팅의 결합 특성이 주로 개선되며, 일부 새로운 특징이 코팅 성능에 추가됩니다. 예를 들어, 나노-SiC, WC, , Al2O3, TiO2, ZnO 와 같은 나노입자는 코팅의 경도를 높이고 PTFE, MoS2, 흑연과 같은 나노입자는 윤활성을 증가시킵니다. 이러한 나노입자 중 PTFE는 낮은 표면 에너지 및 마찰 계수(붙지 않는 표면이나 건조한 윤활유에 좋음), 오염 방지 특성 및 마모 우수성 및 내식성을 포함하여 그 특성 때문에 엄청난 관심을 불러일으켰습니다. Ni-P-PTFE는 고착 방지 코팅으로 사용될 수 있습니다. 외부 층에 있는 이 분자에서 응축된 불소 원자는 낮은 표면 에너지와 매우 낮은 마찰 계수와 같은 PTFE 중합체의 물리적 성질의 주요 원천입니다. 코팅 매트릭스의 PTFE 코드 위치에 따라 Ni-P와 PTFE의 속성을 동시에 사용할 수 있습니다. PTFE는 PTFE 중합체(18.6 mN/m)의 낮은 표면 에너지로 인해 뛰어난 고착 방지 특성을 나타냅니다. Ni-P-PTFE 복합체를 오염 감소에 잠재적으로 적용할 수 있는 분야는 열 교환기의 표면에 석회암과 유사한 퇴적물이 형성되는 심각한 문제에 대한 해결책으로 생각해 볼 수 있습니다. 이러한 침전물들은 여러 종류의 생산 및 가공 장비의 설계 및 작동에 내재된 문제들 중 하나입니다. 이러한 원치 않는 침전물은 다음의 두 가지 방법으로 장비에 영향을 미칠 수 있습니다.
이러한 침적물의 축적을 줄이는 방법을 통해 비용을 줄일 수 있습니다. 우리는 낮은 표면 에너지를 가진 표면에서 이러한 침전물의 접착력이 떨어진다는 사실을 알아냈습니다. 따라서 중합체 코팅이 많이 사용되었습니다. 그러나 기존 중합체 코팅은 기질의 낮은 열전도성 및 내마모성, 낮은 접착력으로 인해 산업에 적용되기에는 한계가 있습니다. Ni-P-PTFE 코팅은 금속 합성물을 기반으로 하기 때문에 열전도성, 기계적 강도 및 내마모성이 PTFE 코팅보다 훨씬 우수하며 표면 에너지도 낮습니다.
Electronless nickel-phosphorous coatings are used widely in many of the industrial applications because the unique properties, including of high wear resistant, high corrosion resistant, highly hard and tough property, and good lubrication. By combining nano–sized particles as a reinforcing phase inside of the Ni-P matrix to obtain functional nanometer composite coating with electronless co-deposition process, the properties of Ni-P coating are to be mainly improved and sometimes new features are fully added to the coating performance. For this purpose, different nanoparticles like nano-SiC, WC, Al2O3, TiO2, and ZnO as harder particles and PTFE, MoS2 and graphite as lubrication particles are added for the coatings.
