PLATING AND ANODIZING: CHROME ALTERNATIVES
Recently, processes have been developed and
processing factors have been determined for
chrome alternatives in the form of metal matrix
composites (MMC). MMC coatings are defined
by material with at least two constituent parts.
They are formed in two phases: a ductile
metallic matrix deposited from the dissolved
ions in the solution, and a dispersed phase
made from the co-deposited particles.
chrome plating typically has a higher co-efficient of friction
than nickel-tungsten, making it less suitable for certain
components. So, instead of it being a case of 'one for all', it is
time to think about 'many for specific'.
Recently, processes have been developed and processing

They are formed in two phases: a ductile metallic matrix

dispersed phase made from the co-deposited particles.
MMCs such as cobalt chromium carbide, nickel tungsten
carbide and nickel chromium carbide can offer unique and
superior characteristics to metal plating solutions including
hardness, wear resistance, and oxidation protection at high
temperatures. When the right combination of materials is
chosen, the properties can be tailored beyond the possibilities
offered by pure metals and alloys.
The fact remains however, that there is a need for an
alternative to hard chrome plating which offers similarly
broad appeal. That solution lies in brush plating with nickeltungsten.
Providing a wide range of deposit properties capable
of meeting a variety of application needs, and with excellent
cohesion and adhesion to the base material, it is equivalent
or superior to hard chrome plating in most respects-and
superior in many. Perhaps the biggest advantage, however, is
the fact it's safe, available and tried and tested in aerospace
applications.
