FriCSo's surface treatment is the leading edge of surface engineering science and tribology. These treatments are based on our technologies and on-going research. 
 

 

Vibrogrooving is a means of surface texturing that is intended to provide an oil reservoir on the metal surface. The additional lubrication retained on the metal surface should improve performance, especially during oil starvation and boundary lubrication conditions. Despite numerous efforts, vibrogrooving has not shown much promise until now. However, when used in combination with FriCSo polymer lapping and careful selection of the grooving pattern, vibrogrooving has shown excellent results in specific applications.

 

During the grooving process, a tool presses on the metal surface, creating a groove by plastic deformation, and raised hardened steel bulges on the sides. The steel bulges must be removed by superfinishing. However, superfinishing leaves sharp edges on the groove. These sharp edges are liable to gouge into the opposing surface. FriCSo's polymer lapping uses a pliable polymer substrate that rounds the edges of the groove. 

 

When the grooving pattern is carefully chosen, vibrogrooving together with polymer lapping has shown significant performance benefits over superfinishing or polymer lapping alone in specific instances. 

 

Selecting the correct vibrogrooving geometry is an imporant factor in achieving optimum results. FriSCo's experience, surface treatment database, and testing facilities can be important assests in helping to select the the most effective geometry for vibrogrooving.
