Benefits

This sintered camshaft gear works at a performance level that was previously restricted to wrought steel. It actually replaced an existing steel gear. The application of surface densification of the flank as well as the tooth root on a prealloyed sintered steel led to a performance level similar to cas hardened steel (e.g. 16 Mn Cr5). To our knowledge it is the first application of a sintered gear for a high performance camshaft drive of an internal combustion engine - several other applications of sintered gears have since been introduced into mass production or are under development
