On the other hand, the achievable surface roughness will ultimately be limited by the material and machining principles.
In addition, shallow features introduce less damage to the surface and subsurface material.
Moreover, the design of surface textures should be related to the type of contact, materials of the interface, and most importantly, operating conditions.

Introduction A promising approach to develop high performance functional/structural materials is to prepare ceramic composites using matrix materials with good mechanical properties and oxidation resistance, with the addition of electronductive phases.
Instead, AlN and MoSi2 follows about the same corrosion rate and the surface material removal results rather uniform.

Abstract.
Intelligent direction of integratability, configurability, adaptability, extensibility and reliability are the developing trends of MES[2,3,4,5,6]. Ⅱ.Tungsten powder processing flow The general production raw material for Tungsten powder processing enterprise(huamao company as example)is Ammonium ParatungState(APT), Tungsten powder processing flow is presented in Figure 1.The fine tungsten oxide can be effectively obtained by calcinations of APT and tungsten powder can be obtained through reducing furnace with hydrogen, After join carbon black, carbonization tungsten powder is formed by carbonization in the carbide furnace.
Products of tungsten oxide and tungsten powder are raw materials of the follow-up process in Figure 1,but also can be sold as product in the same time.
There are some following several difficulties for manufacturing execution management of tungsten powder processing enterprise. 1)Machine capacity of each craft phase has big difference, various Raw materials and finished products, so the processing flow is more complex; 2)Product processing with the characteristic of various small batch, various types and specifications, so planning and scheduling is more difficult; 3)Intermediate products are not only as raw materials of the follow-up process, but also as product for sale, it is important to maintain not only delivery date and quantity with the minimum interim stock, but also optimization and integration of orders in each phases, it is a complex multi-objective scheduling optimization problems. 4) There are not only chemical and physical changes, but also discrete and continuous process flows for tungsten powder processing.

At present, the materials of cutting tools,
drawing die tools, sliding bearings and many kinds of wear resistant components are mostly cemented
carbide (WC-Co).
Drawing wire materials Al-0 and Cu-1 are used as sliding against tools.
This can save more raw materials when the nanocrystalline diamond composite film is used to the drawing die field.

The ideal solutions for the combat resilience design consist of three conflicts: 1) The repair time is short, the repair method of battlefield equipment is mainly changing parts repair; 2) there exists great conflict between Simple repair conditions and good condition after the restoration; 3) it brings difficulties and obstacles for equipment’s combat resilience that fast equipment’s renewal speed, insufficiency security personnel’s ability and deficient combat resilience materials and battle damage assessment.
