ELECTROLESS NICKEL COATING |
Electroless nickel plating is an alloy nickel-phosphorous plating obtained by the catalytic reduction of nickel. Normally electroless nickel plating thickness is limited to 80 microns maximum. Heat treatment is to carry out a degasification and to improve densification and adhesion. The hardness of the deposit varies from 550-650 HV. On heat treatment |
 |
above 290 deg. C, the deposit becomes amorphous and hardness is increased to 950-1000 HV. Hardness of heat treated electroless nickel is superior to hard chrome coatings. |
Features:
- Good wear resistance
- Good anti seizure property
- Good corrosion resistance
- Brighter than electrodeposited Nickel which is slightly yellow
- Deposit thickness uniform over entire surface of substrate almost independent of its shape and geometry.
