Introduction In recent years, brittle materials such as silicon, advanced ceramics, optical glass and Ti-base super alloy have been applied more widely in the mechatronics and electronics industry.
The completion of precision surface grinding is required for good quality of these materials.
However, because of the high hardness and brittleness, these materials are very difficult to machine[1].

XRD patterns showed the prepared material was the complex of Cu2O and NiFe2O4.
In order to overcome the disadvantage and enhance the re-collecting ability, a magnetic material with strong magnetization, such as NiFe2O4, can be combined with Cu2O.

In this paper, simulation by use of ANSYS software, experiment select GH864 high-temperature alloy as substrate material, coating material select Ni78Si19Nb3 by adding appropriate mass fraction of [Nb+C] powder.
Experimental Substrate material: Slect GH864 high-temperature alloy, cladding surface reruires grinding, surface roughness is 0.2 μ m, cleaning with acetone before cladding.
Coating material: Ni powder ([Ni+Co] content ≥ 99.5%, where Co content ≤ 0.5%) , the powder of Si (purity ≥ 90%) ,the purity of C ,Ti and B more than 99%.
Model assumptions: The workpiece is initially at 298K; the substrate and the cladding materials are homogeneous material; the classical heat transfer theory applied in laser material interaction; the workpiece all outer boundary only with the air convection, radiation heat transfer coupled to the convection heat transfer effect; since laser surface modification involves very rapid melting and solidification, convective redistribution of heat within the molten pool is not significant, convective flow of heat is neglected[3].

Introduction The current and predicted growth of the aging population has led to a clinical and socioeconomic need to develop materials, devices and treatments suitable for repairing or regenerating damaged and diseased hard tissues.
Tissue engineering has been described as "applying the principles and methods of engineering, material science, and cellular and molecular biology towards the development of viable substitutes which restore, maintain, or improve the function of human tissues" [1].
Whilst most tissue engineering scaffolds currently being investigated are polymeric, there is also considerable interest in bioglasses / bioceramics where hard tissues are concerned, since such materials are known to form a direct bond to bone.
However, that work did not involve combining our materials with either cells or growth factors.

Theory of silt brick-making and cutter The main raw materials of mud sintered porous bricks are silt, coal gangue and something used to make micropores, they are mixed at a certain proportion, stirred, extruded, cut to prepare for making silt-bricks.
Many producers add some combustible materials such as waste paper, waste wood chips, packaging rubbish and straw to the adobe, and then sintering bricks can form tiny holes in order to achieve the purpose of heat preservation and heat insulation.
