||Corrosion (rust) on unprotected parts or zinc plated parts. Paint
chipping and general deterioration over time. Hard to clean &
||Coating of approx. 10 mm high phosphorous ENi
||Provided corrosion resistance, wear resistance and ease of cleaning
||Excessive wear around seal area
||New shafts made allowing for 50 mm deposit of ENi and harden to 65 RC
||Wear at this area has been improved dramatically. Life of parts extended to the point where seals wear out first
||Previously nitrided and then hard chromed. Although wearing well, corrosion evident around seal areas
||Samples machined to allow for 50 mm deposit of ENi then hardened to 65RC
||Wear characteristics maintained. Corrosion no longer a problem. Life of parts extended.
|Threaded drive screw (brass)
||Parts running on plastic which was picking up brass particles from
the screws creating excessive wear on the plastic running surface
||5-8 mm deposit of ENi on brass screw
||Harder ENi coating eliminated "pick up". Also increased life of parts and provided corrosion resistance.
