Electroless Nickel describes the plating of nickel deposits, which may contain phosphorus, onto catalytic metallic substrates by chemical reduction.
Substrates can be: Steel, stainless steel, aluminum, copper and alloys...
UNIFORMITY OF THE DEPOSIT, even uniform in complex geometries.
HIGH ACCURACY WITH TOLERANCES OF +/- 1 microns.
HIGH RESISTANCE TO THE CORROSION. Deposits are often less porous and thus provide better barrier corrosion protection to steel substrates, much superior to that of electroplated nickel and hard chrome.
The deposits cause about 1/5th as much hydrogen absorption as electrolytic nickel and about 1/10th as much hard chrome.
Deposits can be plated with zero or compressive stress.
Deposits have inherent lubricity and non-galling characteristics, unlike electrolytic nickel.
Deposits have good wet ability for oils.
SODERABILITY. In general are considered solderable.
HARDNESS. Deposits are much harder with as-plated micro hardness of 450 - 600 VPN which can be increased to 1000-1100 VHN by a suitable heat-treatment.
Mechanical pre-treatments, such as grinding, polishing or blasting are usually required. We obtain materials brilliant, buff or satin.
