Introduction Morphological control of monodisperse, anisotropic single crystals of metal oxides has been an important issue in the materials industry during the past few decades. α-alumina is one of the metal oxides most widely used in applications, highly important in many fields of electronics and engineering, such as catalysis, microelectronics, lasers, optics, refractories, but the different Morphology is required according to different usage, spherical particles are good for packing while molding in ceramic preparation process, platelet particles are efficient on polishing, while elongated grains introduced as the second phase can function as reinforcements similar to whiskers or fibers in reinforced ceramics which can improve the fracture toughness appearently. α-alumina particles have been synthesized with many methods and show different morphologies synthesized with different additives.
The energy at the surface (SE) can be calculated thus: SE = (Esurface - N*(Ebulk/n))/(2*A) (1) where N is the number of atoms in the Surface cell, n is the number of atoms in the bulk cell, and A is the area of the surface.The surface area for this system can be found in this manner: A=a*b * sin(γ) (2) Results and Discussion Calculation result.

Wk = λk / (2) Among them, i is the main component analysis according to the number of principal component principal component variance contribution rate selection.

It illustrates that all the density numbers of ternary boride hard alloy are less than that of the general hard alloy and about equivalent to that of steel.
The density number is about 7.5~8.
The grain boundary of combine between the horniness phase and the bonding phase base Fe is very obvious and compact, and the void radio is lower.

At present, there are a number of papers published about the magnetic properties, butylene dehydrogenation and other contents of ZnFe2O4 materials [3].
According to the Scherrer formula calculation, the grain size was about 29.5nm.
Fluorescent light, which had the longer wavelengths and the lower loading voltage, was used, the number of the excitation light free electrons and holes was small.

A number of studies have been done to investigate the impact factors on the material removal.
Experiment and Results A number of planner specimens were prepared with the same material, dimension, and machining process.
In the polishing process, diamond paste with a grain size of 0.5µm was used, and Kw for aluminum was obtained as .

These are the rules of success for the majority of production procedures, i.e. to make the maximum number of projects per unit of time.
Samples were then preserved in dentacryle and prepared via the defined metallographic procedure (sharpened with 240, 400, 600 and 800 type sandpaper, dampened with water, polished with diamond paste, 1/0 grain on satin dampened with kerosine, washed and rinsed in benzine alcohol).
Fig. 4 Recordings from the measurement of surface roughness for selected samples Conclusion The following conclusions for theory are derived from the results of experiments : · definition of conditions for achieving productive drilling, · determining the impact of changing the number of created holes on the accuracy of the produced diameter, · achieving hole accuracy under H7, · verifying new progressive structures with the aim of eliminating negative effects, Increased demands on the quality of holes calls for considering a series of factors, for example: · the drill must be checked on a regular basis, throughout the entire service life of the tool, to ensure its reliability and long service life, · the type of drill and its geometry (mainly the primary cutting edge angle) impacts the quality of making holes

Ferrous powder (laser form ST 100) of 20 mm grain size with a polymer binder of 3 mm is used for the manufacturing of the specimens which is later infiltrated with Bronze.
Since there are a number of variables, factorial design approach was used for designing the experiment.
Fig. 3 SEM images of lateral surface of specimens Conclusions A number of test specimens (manufactured by SLS technology) were evaluated to determine the surface roughness and topology on the lateral surface along the built direction.
