| Abstract: Ion beam modification of noble metal electrical contact coatings can
achieve suitable friction and wear behavior with inherently stable low
ECR. For example, this method of producing Au electrical contact coatings
can produce wear properties similar to electroplated hard Au, but without
the environmental concerns due to stringent OSHA regulations on the use
and disposal of toxic chemicals associated with Au electroplating baths.
Integration of physical vapor deposition techniques with ion implantation
can produce noble metal coatings with surfaces modified to achieve the
desired balance between adhesion/friction/wear and electrical contact
resistance on a commercial scale. |
