abstract = {An overlay coating against wear or corrosion on components
is required for various technical applications. Thermal
spraying is a well-established and near-net-shape deposition
method. In this work, high-velocity oxy-fuel spraying of two
different ledeburitic cold-work tool steels was employed to
produce wear-resistant Fe-base coatings on a stainless steel
substrate. This work focuses on the investigation of
diffusion processes across the coating/substrate interface.
Specimens were heat-treated for different dwell times and
then analyzed by means of EBSD, XRD, OM, as well as SEM.
Results of phase formation and diffusion profiles were
compared with equilibrium and diffusion calculations
obtained with ThermoCALC (R) and DICTRA (R). The influence
of diffusion processes across the coating/substrate
interface on the mechanical properties, such as adhesive
bond strength and hardness, was investigated by shear tests
and microhardness profiles.},
