项目摘要

Employing mechanical alloying method to mix hard chromium carbides serious phase and soft Fe-Cr alloy serious phase in the level of hyperfine structure, to develop a new heat resistance and wear resistance composite material that contain new composite phase in structure. The present application is that use ash treatment subject in coal burning thermal power generation plant and in coal gaseous furnace, and pipe, where occurred particle erosion by solid and gas flow, as target, to develop a heat resistance and wear resistance composite material which is of resistance to erosion of coal ash even in the temperature of over 800 centigrade, and then evaluate the practice using of this kind of material by high temperature erosion test.In the present research, we employed a high temperature erosion test machine that correspondent to low stress impact condition. The apparatus is the revolution style where the specimen was buried in constant high temperature particles layer on the assumption of … More how the wear occurred by dispersed particles in high temperature. Holder of specimen is a thick heat resistance stainless steel that has nice rigidity in high temperature. The shape of specimen is a cylinder of outer diameter 30mm, inner diameter 20mm and height 20mm. The specimen is set on shaft bearing of holder, supported by a ring for fixing and plate bolt at below, to carry the erosion test. When doing test, before insert specimen into holder, use rotating arm that has same shape of specimen holder to stir the particles layer carefully, and when the temperature in gap get to flat the specimen holder is inserted to replace the rotating. Silver sand no.3 (average diameter is 2mm) is used as impact particle. In the testing machine, the maximum test temperature is 850 centigrade, maximum specimen rotating speed is 500 rmp, and speed of specimen relative to particles is 3.3m/s. The results of test showed that the faster circumferential speed is, the more the amount of abrasive wear is. The harder the material is, the less the amount of abrasive wear is. Moreover, when the matrix structure is austenite, through sliding wear, the austenite change to martensite owing to happened strain induced transformation and so that restrain abrasion.According to the result above, when use abrasive wear testing machine in normal temperature, the elements such as circumferential speed, the property of testing material (especially hardness, structure) etc. become of more importance.

采用机械合金化的方法，在超细组织水平上混合硬质碳化铬严重相和软质Fe-Cr合金严重相，开发出一种在组织上含有新型复合相的新型耐热耐磨复合材料。本课题的应用是以燃煤火力发电厂、煤气炉和管道中存在固体气流和气流颗粒侵蚀的灰处理课题为对象，研制出一种耐热耐磨复合材料，该复合材料在800℃以上的温度下也能抵抗煤灰的侵蚀，并通过高温侵蚀试验对该材料的实际使用情况进行评价。在本研究中，我们采用了适合于低应力冲击条件的高温冲蚀试验机。该装置为旋转式，在假定颗粒在高温下分散的情况下，将试样埋于恒定的高温颗粒层中。试样支架采用厚耐热不锈钢，在高温下具有良好的刚性。试件形状为外径30mm，内径20mm，高20mm的圆柱体。试样安装在支架的轴轴承上，下部由固定环和板螺栓支撑，进行冲蚀试验。在进行试验时，在将试样插入试样架之前，使用与试样架形状相同的旋转臂仔细搅拌颗粒层，当间隙温度趋于平缓时，插入试样架以替代旋转。银砂三号（平均直径2mm）作为冲击颗粒。在试验机中，最高试验温度为850℃，试样最大转速为500 rpm，试样相对于颗粒的速度为3.3m/s。试验结果表明，周向转速越快，磨料磨损量越大。材料越硬，磨料磨损量越小。当基体组织为奥氏体时，通过滑动磨损，奥氏体因发生应变诱导转变而转变为马氏体，从而抑制了磨损。综上所述，在常温下使用磨料磨损试验机时，周向速度、被测材料的性能（尤其是硬度、组织）等因素显得尤为重要。少
