Wear resistance and service life of disc cutter are improved by matching the materials of disc cutters with rocks.
The results are useful for structural optimization and strengthening treatment of material of disc cutter.
Material of the cutter ring is linear elastic material.
The stress of disc cutter occurs at right side, left side and top too, besides at foot of the cutter ring; 3) For different rock, different material for the cutter ring must be chosen.

Introduction Titanium nitride(TiN) films play an essential role in contemporary microelectronics as diffusion barriers, in the automobile and glass industries as reflecting materials, in jewellery as gold-colored surface-finishing paints[1-3].
Their main field of application is in the machine industry as refractory materials and as hard and wear-resistant coatings on machine tools and mechanical parts[4-7].

The research of deformation resistance show that not only the flow stress and plastic workability depend on chemical composition of material and microstructure, but also some external factors such as deformation temperature, strain rate, strain, stress state and environmental medium play a very important impact on the mechanical properties of material.

Experiments (1) Materials The chemical analyses of CFBC ashes are given in Table 1.
The CFBC fly ashes were tested as-received, and the CFBC bed ashes were ground and sieved to remove material above 80μm size fractions.
Fig.3 Relation between free lime content and SO3 content ③ Effect of the high-activity components on the hydraulic strength of CFBC ashes The contents of Portland cement clinker in the blends of Portland cement and pozzolanic materials can be determined based on the fact that Portland cement clinker is active enough to be soluble in low concentration hydrochloric acid at lower temperature, while pozzolanic materials are not [5].
