Such equipment is well suited to crankshaft hardening treatment.

The method may include treating the bearing rings in a peening treatment and then in a duplex hardening treatment.

The method may include treating the bearing rolling elements in a tumbling treatment and then in a duplex hardening treatment.

The composition is then cured to provide enhanced fire resistance.

The superalloy is an Inconel that has undergone a structural hardening treatment after machining.

At least partially curing the resin by subjecting the resin to a first cure treatment (36) and at least partially curing the resin by subjecting the resin to a second cure treatment.

Preferably, the heat-shielding member (3) is positioned outside the cure chamber (11) during a part of the cure treatment.

Provided are: a metal material, the wear resistance of which has been enhanced by hardening the surface layer; and a surface-hardening treatment method therefor.

The support is adapted to rotate the metallic part (20) during a hardening treatment.

The surface of the base metal has been subjected to hardening treatment by at least one of nitriding or carburizing.

The strip is obtained by hot-rolling above 950 °C, then cold-rolling and carrying out a hardening treatment between 450 °C and 850 °C, the hardening heat treatment being preceded by a reduction of at least 40 %.

In some cases, heat treatments such as solution heat treatment or artificial aging hardening treatment are performed after casting.
