The electrical explosion coating technology was used for the surface consolidation of the die, the material of the coating was 2Cr13. The coating was detected and analyzed by scanning electron microscopy, energy dispersive spectroscopy and strength test. The results show that the coatings are dense with no micro-cracks, less cavity and alloy element losses and the coating and substrate has a high bonding strength. The mold strengthened by biomass particles forming after the electrical explosion spraying 2Cr13 was examined in production.Its life can be doubled.The experimental and production result provide the basis for adopting “ordinary steel + electric explosion spraying surface hardening process” instead of making the mould with the expensive mold steel.
