Load of high abrasive wear of chromium cast iron

l. Expressed as the load increases as the wear volume is also increasing, when the load increases a certain value. Acting on the exposed carbides also increases the force that started out smaller carbide matrix in Figure 2, because the smaller the carbide and the substrate binding between the smaller size. Binding is relatively small. Load further increases. Larger carbon \Gradually began to peel the substrate. Loss can not be self-carbide protective Mi F body, which resulted in a sharp increase in wear, and as for the force on the River in the carbide increases. The larger carbide is brittle fracture and spalling,[link widoczny dla zalogowanych], further exacerbating the wear. The \\With the load increasing size of the larger pieces of carbon began to peel the base,[link widoczny dla zalogowanych], and IP, is fragmentation. This requires high-chromium cast iron carbide not only evenly distributed and have the right size. . (3) high chromium cast iron have a certain amount of residual austenite. Retained austenite can better support the carbide.

Extension is soil or Calcined bauxite mine tailings as raw materials. The components include: 70 ~ 80% of alumina, silica 10 ~ 2O%, oxide edge <5%, titanium dioxide <5% . The preparation methods are: bauxite in the�� 0oO ~ 1400 �� _ cockroach under the burning 1 ~ 2h: the calcined bauxite calcined bauxite tailings f or take other production processes is waste) electric arc Jealous spit in the molten state of the ball: to bite into the enamel screening, take 0.1 ~ 29mm particles. that is prepared soil heavy sand cast aluminum ball Tong finished its advantages are: good temperature resistance, strong collapsibility, good mold release, silt, volatile low. mechanical strength, a rich source of raw materials, low cost, high precision molds for Patent Name: homes hypereutectic A1.Mg2SiSi barrier complex boasts fine Ce S BU processing of patent applications I Art: 03l16988.0: set to open No.: CN1472355 Date :2003-05 Fortunately, please a I6: Open Date :2004-02.04 Applicant: Shanghai Jiaotong University, a spit of hypereutectic A1.M Si.Si homes thinning barrier Sr.Ce compound I belong to multiple homes arts materials in the field. The present invention uses metal and rare earth Ce sr composite elements added Jing. in which the weight percentage of Ce 0I ~ I.3%. Sr mass ratio 06 ~ O.8%, deal with hypereutectic Al-M alloy SiSi snake, and ultimately a significant refinement of particles of the present invention Mg2Si enhanced Sr-Ce composite added by Jing-treated eutectic A1.Mg2Si.Si alloy. to completely suppress self Msi dendrite growth trend, and thus significantly reduce the increased body size (15 cape below), and to improve the reinforcement of the form. in alloy solidification in a large amount of short rod-like MSi reinforcement, so that This material is more in line with particle reinforced metal matrix composite applications \
