GSD-02 Load Bearing Capacity of Surface-Rolled High Density Sintered Metal Gears(gear Strength and Durability, Including Gear Materials and Heat Treatment Techniques)

Study on the rolling friction and wear properties of surface densified powder metallurgy Fe-2Cu-0.6C material

“…where ρ 0 , E 0 and ν 0 are the density, elastic modulus and Poisson's ratio of wrought steel, E and ν are the elastic modulus and Poisson's ratio of PM Steel with a sintered density of ρ. In consideration to surface densified materials, it is reasonable to assume the use of wrought steel elastic properties [15]. In this paper, the elastic property of the densified material can be described by the elastic modulus and Poisson's ratio of wrought material which is 207 GPa and 0.3 respectively.…”

The Effect of Rolling Temperature on the Microstructure and Mechanical Properties of Surface-Densified Powder Metallurgy Fe-Based Gears Prepared by the Surface Rolling Process

“…Gunter et al [10,11] proposed a densification strategy to achieve PM gears with high load-carrying capacity; Takemasu et al [12,13] studied high-performance PM gears. Jones et al [14] and Koide et al [15] studied high-performance, surface-densified PM gears. Those studies indicated that a densification depth of 0.2-1 mm was formed on the surface layer with an obvious increase in density and surface hardness.…”
