      abstract     = {The aim of the present study is to develop a Fe-based metal
                      matrix composite (MMC) coating using high velocity oxy-fuel
                      spraying (HVOF) process. A ledeburitic high alloyed cold
                      work tool steel (X220CrVMo13-4) and NbC with an average size
                      of 2 mu m at different volume fractions have been considered
                      as metal matrix and hard particles respectively. MMC
                      coatings were deposited on austenitic stainless substrates
                      and the coatings were subsequently densified by hot
                      isostatic pressing (HIP) with and without encapsulation.
                      Microstructural analysis of the as-sprayed and HIPed
                      coatings were characterized by SEM and XRD methods. Results
                      showed that the feedstock preparation involving fine NbC was
                      an influencing factor on the coating deposition. A
                      relatively homogeneous dispersion of fine NbC up to 30
                      $vol.\%$ in cold work tool steel matrix was possible using
                      optimized HVOF spraying. Besides, HVOF spraying and its
                      subsequent HIP treatment induced significant microstructural
                      and phase changes in the MMC coatings. The study showed the
                      potential of HVOF spraying for the development of steel
                      based MMC coatings and its subsequent densification can be
                      achieved by HIP process with and without encapsulation. (C)
