Corrosion resistance
(to avoid becoming dilapidated due to rusted)

Category of plating characteristics Purpose (applicable examples)
Nickel plating
(gloss ・semi gloss・ matt)
・ Good corrosion resistance ・ Precision optical instruments and apparatus
・ Interiors of computer
・ Various ordinary articles
Electroless Nickel plating (KNi)

・ Hardness
・ abrasion resistance
・ homogeneity
・ weldability
・ ductility

・ electronic equipment
・ semiconductor instruments and apparatus
・ computers
・ instruments and apparatus for computation
   and measurement
Copper plating ・ Increasing adhesion of
   material
・ preventing cementite
・ corrosion resistance

・ mechanical parts

 

Lubricity

Category of plating characteristics Purpose (applicable examples)

Lubrication plating

TM-AF (Grey)
TM-BF (Black)
H-TM-F (Hard)

・ 20~24vol% of PTEE is contained in film.
・ Excellent abrasion resistance, mouldability, smooth and flat. Its special treatment for better initial grinding is another characteristic.
・ With plating film under separating state, the hardness can reach Hv500~550 by Hv350 heat treatment

・ To control heating of interiors of office equipment due to friction, and prevent producing noise
・ bearing, piston ring and piston, etc.
・ turbo worm device, crankshaft, etc.
・ coating product of solid lubrication surface starts using lubrication plating treatment process.
  In addition, if PTEE coating is used for parts and components of office equipment, if PTEE coating is covered, the mechanical strength can be increased and has the advantage of not having electrostatics.
In parts and components for precision optical instruments and apparatus, it can suppress metal noise, in environment oil is not allowed, it is expected to treat the parts and components instead of oil, is a power measure for forbidding oil.

 

Optical property

Category of plating characteristics Purpose (applicable examples)
Light absorption
Black nickel plating ・Nice looking ・ Avoiding reflection light ・Interiors of precision optical instruments and apparatus
Sn-Ni plating ・Corrosion resistance・Durable color
・Excellent welding performance of
  hardness HV300〜350
・Decoration products・Interiors of telecommunication products
Light
reflection

・ abrasion resistance
・ light reflective
・ ear themometer IR reflector
Silver plating ・ Conductivity
・ nice looking
・ light reflective
・ searchlight reflector parts
・ mirror surface of reflective
   devices
