Special Plating for Automotive Parts of KANZACCWhisker Free Plating Film “HYDRO-C2” for Connector of SRC
The HYDRO-C2 is a very good whisker free partial platingprocess used for the jointing terminal of the Steering Roll
Connector (SRC). The whisker free plating film
“HYDRO-C2” is plated on the fitting part to prevent generation of the whisker at the fitting part. By this plating film,
the fitting part maintains the electrical property and theeasiness of insertion and extraction.
On the other hand, the working part has no plating but
is designed to inhibit the oxidization of the surface and tomaintain a good workability of the welding.
Figure 1 shows the jointing terminal in the SRC. Figure

2 shows the example of the whisker occurring on the surface of the plating. It is a mustache-shaped metal crystal
and causes the electrical short.

Abrasion Resistant Plating Film “GAN:coat” for Retainer of Connecting Rod
Abrasion resistant plating film GAN:coat has neither peeling off nor pollution of the engine oil because of no sulfurization by the engine oil, comparing with the copper plating or the silver plating. Since GAN:coat has also lower adynamic friction coefficient compared to the copper plating or the silver plating, it has a good resistant to abrasion, and the coat is the most suitable in the surface plating of the retainer of the connecting rod.
Figure 3 shows the connecting rod and the retainer andFigure 4 shows the comparison of the abrasion loss andthe dynamic friction coefficient between the GAN:coatand the copper plating or the silver plating.
Featuresa.	No peeling off because of absence of sulfurization by
the engine oilb.	Low dynamic friction coefficient and a good resistance to the abrasion

Abrasion Resistant Silver Plating Film “anga-U plus”
for Charging Connector of EV
The anga-U plus is a new silver plating with resistance tocutting and abrasion as compared to the conventional silver plating. It is suitable in applications of EV charge connector requiring long term insertion-extraction. The anga
U plus maintains low contact resistance for a long term,
because only a little abrasion is caused by repetitiveinsertion-extraction.
Thin plate film is possible because of the small abrasion
loss of anga-U plus. This feature can greatly contribute tocost reduction.
The image of the charging connector of the male andfemale terminals plated with the anga-U plus is shown in
Figure 5. Figure 6 shows the variation of the contact resis-↑tance versus repeated insertions and extractions for theanga-U plus plated connector and for the conventional
silver plated one.
The increasing of the contact resistance of the anga-Uplus plated is smaller than the contact resistance of theconventional silver plated.
Featuresa.	The contact resistance increase is low because of agood resistance to abrasionb.	The cost reduction can be achieved because of thethinner plating
