The present application provides a method for preparing a rare-earth permanent magnetic material with grain boundary diffusion using composite target by vapor deposition, in which the composite target is evaporated and attached to the surface of the NdFeB magnet, and in which medium-high temperature treatment and low temperature aging treatment are employed, resulting in that the coercive force of the magnet is improved significantly and the remanence and the magnetic energy product substantially are not reduced. The advantageous effects of the present application is as follows: the coercive force of the magnet is improved, and meanwhile the defects such as melting pits and crystal grain growth and the like caused by high temperature treatment for the long time are eliminated, and the usage amount of heavy rare-earth is greatly reduced, thereby lowering the cost of the product.

The influence of the electromagnetic fieldon the synthesis and properties of the AlTiN coatings,deposited by cathodicarc ion plating was investigated with charge coupled device camera,X-ray diffraction,scanning electron microscopy and conventional mechanical probes.The results show that the voltage powering the EM field has a major impact on the motion of arc-spot,film growth,microstructures and mechanical properties.To be specific,as the voltage increased from 10 to 30 V,the arc-spots,with increasing spot number and moving at faster speed,shifted from the target edges toward the center; the deposition rate increased,accompanied by formation of small grains; its Vickers-hardness increased but the friction coefficient decreased.A voltage increase above 30 V increased the friction coefficient but weakly affected the deposition-rate,grain-size and hardness of the AlTiN coatings.Possible mechanisms responsible for the observation were briefly discussed. © 2016, Science Press.

La0.75Mg0.25Ni3.2−xCo0.2Al0.1Mox (x = 0, 0.10, 0.15, 0.20) hydrogen storage alloys were synthesized via vacuum induction melting combined with a heat-treatment at 1173 K for 8 h. All alloys have multiphase constitutions including (La, Mg)2Ni7, (La, Mg)5Ni19, LaNi5 phase and there is residual Mo phase in the Mo-added alloys. Increasing Mo content, the abundance of (La, Mg)2Ni7 and (La, Mg)5Ni19 phase with super-lattice stacking structure initially increases and then decreases while that of LaNi5 phase shares a reverse trend. In all Mo-added alloys, Ni is partially substituted by Mo leading to an overall expansion in unit cell volumes. The electrochemical analyses show that the cyclic stability of the alloy electrodes are significantly improved after Mo is added especially when x = 0.15 the cyclic retention is 80.9%, which is 16.4% higher than that of the original one. The maximum discharge capacity are almost unchanged between the alloy electrodes for x = 0 and x = 0.15 while the high-rate discharge ability at the discharge current density of 1500 mA/g is enhanced from 55.2% to 60.1%. The comprehensive electrochemical properties reach a compromise for La0.75Mg0.25Ni3.05Co0.20Al0.10Mo0.15 alloy electrode which possesses remarkably improved cyclic stability, enhanced kinetic property and maintains almost unimpaired discharge capacity in the meanwhile. © 2016 Elsevier B.V.

The present invention provides a fluid filter utilizing a polymeric membrane supports by metallic screens contained in a housing. The supports have apertures through which fluid can pass. The metallic supports are created such that they have at least one surface substantially free from burrs, so as not to damage the membrane. This smooth surface is in communication with the polymeric membrane. One or more indexing protrusions can be added along the circumference to restrict the relative movement between the supports, and to align the apertures of the two supports.

Effect of diamond pattern on cutting performance of saw blades were investigated, as well as the formula to calculate the concentration of arrayed diamond. Three kinds of saw blades were used in the test to cut reinforced concrete. Results indicated that, with diamond concerntration of 20% and the same matrix and diamond grade, the cutting speed of four-layer structured diamond saw blade increased by 13.8%, but its tool wear increased by 13.3%; the cutting speed of five-layer structured blade increased by 34.8%, and the tool wear decreased by 17.3%. This showed that the rational structure of diamond saw blade could improve the efficiency and life, but the irrational structure would shorten the life. ©, 2014, Zhengzhou Institute of Abrasives Grinding.
