abstract = {Thick (2-3 mm) Fe-base coatings with admixed ferrotitanium
(Fe30Ti70) were applied to austenitic steel by a
high-velocity oxy-fuel process (HVOF). Hot-isostatic
pressing (HIP) was carried out to the decrease porosity and
to increase the material strength, wear resistance, and
adhesive bond strength of the deposited coating to the
substrate material. SEM and XRD investigations confirmed the
formation of hard titanium carbide (TiC) particles during
HIP treatment as a result of strong carbon diffusion out of
the metal matrix and into the Fe30Ti70 particles. The
mechanical and wear properties of the densified coatings
were investigated by means of shear tests, hardness
measurements, and abrasive wear tests. A comparison of the
coatings in the as-sprayed and the HIPed state showed a
large increase in the wear resistance due to in situ TiC
formation.},
