MAF can be used to finish nonferromagnetic materials and ferromagnetic materials, but the magnetic flux density distributions of finishing two materials are different.
Performance of Finishing Nonferromagnetic Materials and Ferromagnetic Materials With the cylindrical magnetic abrasive apparatus designed and made by the author, a series of experiments on finishing the cylindrical surfaces of nonferromagnetic materials and ferromagnetic materials are carried out.
The 45-steel (ferromagnetic materials) and the 1Cr18Ni9Ti stainless steel (nonferromagnetic materials) are chosen as experimental materials.
The amount of material removal of finishing nonferromagnetic materials is much less than that of finishing ferromagnetic materials, even if the speed of finishing nonferromagnetic materials is faster than that of finishing ferromagnetic materials and the time of finishing nonferromagnetic materials is more than that of finishing ferromagnetic materials.

Finally, the thesis summarizes: LCA is not only applied to technological sciences and natural science, but also is applied extensively to social science, economic science, management science and international relationship etc; The implementation of LCA not only depends on LCA standard, but also depends on the implementer's exact understanding of method and target and one's own experience and technological background, and there is much limitation mainly in practical application.
The total life cycle of the products, craft or behavior includes exploitability and processing of raw materials, production, transportation, distribution, use and regeneration, maintenance, recycling and final disposal of products etc."
As a kind of principle and method of product assessment and design at present, LCA is not only applied to technological sciences and natural science, but also is applied extensively to social science, economic science, management science and international relationship etc. (1) Application to the department of industrial enterprise.
One intact LCA case research needs a large number of basic data, which makes data materials being hard to obtain unavoidably.

So, the specimen is untreated material and materials that was repeated 1 to 3 cycles in polymer impregnation and pyrolysis.
Fig.1 shows the cross-sectional image of specimens after melt impregnation that is untreated material and repeated polymer impregnate and pyrolysis materials.
Bonding force between the layers of the composite materials is increased by filling carbon.
Using HfC can improve heat resistance compared with the conventional materials.
