The die failure begins from the surface, so, for the purpose of saving energy and source and exerting full potential properties of materials, surface modification treatment on H13 steel die is necessarily been carried out as the key method to increase the service life of die.
The materials synthesis and synthetic materials sediment can be simultaneous, the ceramic phase is synthesized by in-situ synthesis with a fine grain size and the bonding with metal substrate is good[12-16].
Experimental procedure The raw materials for preparing coating include: powders of 30-50 µm Mo、40-60 µm Cr、30-50 µm Ni and 50-70 µm Fe,as well as 30-50 µm FeB.
