詳細(xì)介紹

涂層特點(diǎn)

以PTFE為基礎(chǔ)添加Ni等其他金屬元素,具有極高的化學(xué)穩(wěn)定性,同時保證優(yōu)良的耐磨性和抗腐蝕性,兼具低的摩擦系數(shù)和良好的自潤滑性。

Nickel–PTFE(Teflon)Plating (Ni-Te)

Polytetrafluoroethylene also known as P.T.F.E. It is a high polymer chemical consisting of fluorine resin. More than 1 ethylene hydrogen atom is replaced by fluorine atom; P.T.F.E. is a polymer that has millions of macromolecules. It is heat resistant, oil resistant, and chemical resistant and is not affected by almost all solvents.

●Nickel–Teflon Plating

P.T.F.E. as a solid lubricant disperses its P.T.F.E. particle uniformly over its Nickel Teflon film. It is a perfect self-lubricating film. When P.T.F.E. coated metal is rubbed against each other the P.T.F.E. particles disperse and spreads out thus reducing friction and prevents sticking.*(μ)

Nickel metal becomes the matrix which contains phosphorus so the film is hardened by the heat during heat treatment.

Indicator of the characteristics of Nickel-Teflon plating under the various conditions.

*Appearance of the surface and coefficient at friction by heat treatment(cf. figure 1)

After Nickel-Teflon plating at 10μm completed the P.T.F.E. particles that are exposed dissolve at the temperature at 350℃and change its form into fan shape, this further decreases the frictional coefficient.

*Temperature of heat treatment and hardness(cf. figure 2)

After Nickel-Teflon plating at 3μm, the Nickel-Teflon plating shows the hardness at 300Hv under the condition of eduction. After heat treatment of 300℃x1Hr the hardness achieved is 550Hv. This hardness is the appropriate hardness.

*Thickness of plating film and hardness(cf. figure 3)

When the thickness of Nickel-Teflon plating is 20μm or over it achieves the same strength as just Nickel-Teflon plating.
