TiC coatings on high carbon steels are suggested to improve wear resistance as well as resistance to corrosive atmospheres. However, coating high carbon steels with pure TiC is technically difficult due to the rather strong affinity of Ti to N 2 , O 2 or H 2 . A coating reagent including mainly ferro-Ti, A1 2 O 3 and small amount of NH 4 C1 was applied to two high carbon steels of SK3 and SKS93 at various temperatures and time periods in a closed crucible . The layers were inspected under the microscope and their hardness profiles determined. The TiC coatings were also identified by X-ray diffraction and EPMA
