ABSTRACT AISI H13 hot-work die steel has proved to be a promising material for hot work
die making. Still, there are challenges in using H13 steel, with an impressive advancement …

In this work, the tribological performance of borided and untreated AISI H13 steels under dry
and lubricated conditions was studied. The formation of the boride layer on the AISI H13 …

Wear behaviour of quenched and tempered (QT) hot work tool steels (Uddeholm QRO90)
was investigated against SAE 52100 grade bearing steel balls after gas nitriding using a …

The purpose of duplex surface engineering involves a sequential application of two surface
technologies in order to develop a surface with combined properties. Duplex treatments …

The influence of plasma nitriding and gas nitriding processes on the change of surface
roughness and dimensional accuracy of 42CrMo4 steel was investigated in this paper. Both …

Surface treatments have been vastly used in the manufacturing industry to improve the life of
tool materials. Plasma nitriding (PN) is widely used because it allows controlling the surface …

AISI H13 steel was subjected to boriding and nitriding; its performance was evaluated by the
progressive load scratch test, and then by the multipass scratch test (MPST), to evaluate the …

Plasma nitriding (PN) coupled with physical vapor deposition (PVD) has emerged as one of
the promising surface treatments to achieve an elevation in the tribological, oxidation …

This paper presents an auxiliary heating method to maintain a uniform specimen
temperature and precisely control nitriding temperature during plasma nitriding. The surface …

During hot forging/forming operations, the die surface and near surface region is subjected
to severe wear. The failure of dies originates from the surface region. In this research work …
