High performance sintered steel gears for use in transmissions and machinery – a critical review High performance sintered steel gears meet wrought steel gears!
Except for high-end gear applications in automotive and aerospace transmissions, high performance sintered steel gears meet wrought steel gears in respect to gear strength and geometrical quality. The performance increase has to thank advances in powder metallurgy in last two decades such as selective surface densification, new materials and lubricants for high density-, warm- and warm die pressing. This review lists results of a decade with high performance sintered steel gear prototypes development at Hoganas AB in Sweden.
