Details of Ni-P / PTFE composite plating

Ni-P / PTFE composite plating is an electroless plating film based on metal (Ni-P), so it is characterized by a higher film hardness than coating films such as Teflon coating (fluorine coating). In addition, even if the film is scraped, the PTFE is evenly dispersed in the film, so it is possible to maintain the characteristics until new PTFE appears on the surface layer and the plating film disappears.

It is sometimes called Nimflon, Kaniflon, Nimtech, etc., but Nimflon is the drug name of Uyemura & Co., Ltd., Kaniflon is the drug name of Japan Kanigen Co., Ltd., and Nimtech is the product name of Shimizucho Metal Plating Co., Ltd. We are here. Both chemicals are the same Teflon electroless composite plating chemicals, but their performance is slightly different due to the slight difference in the composition of the chemicals.

複合めっきとは、めっき皮膜中に別の材料の粒子が入っためっき皮膜を指します。断面画像①はテフロン無電解複合めっき皮膜の断面画像になります。金属のめっき皮膜中にフッ素粒子が混在することで、新たな特性を持つ皮膜ができます。​

テフロン無電解複合めっきとは、無電解ニッケル(Ni-P皮膜)にPTFE(ポリテトラフルオロエチレン=通称テフロン)の粒子をめっき皮膜中に分散し複合共析させためっき皮膜です。

ポリテトラフルオロエチレン (polytetrafluoroethylene, PTFE) とはテトラフルオロエチレンの重合体で、フッ素原子と炭素原子のみからなるフッ素樹脂(フッ化炭素樹脂)でテフロン (Teflon) の商品名で知られています。

化学的に安定で耐熱性、耐薬品性に優れた材料です。

It is a cross-sectional image of Ni-P / PTFE composite plating.

What looks like a black cavity in the film is PTFE (polytetrafluoroethylene) particles, and the other parts are Ni-P metal films.

The average particle size of the particles is 0.2 μm

The general film thickness of Ni-P / PTFE composite plating is 10 μm.

(Actual film thickness: minimum 1 μm to maximum 30 μm)
