The CA_6 crystallized from calcined bauxite has been investigated by means of chemi-cal analysis,optical microscope,XRD and SEM. From the chemical composition, it is foundthat,in spite of the presence of more CaO compared with the theoretical value and of smallamount of oxides of Fe and Ti in solid solution with CA_6, the optical constants of theCA_6 mixed crystal, however,are not effected, i.e., (一)2V=0; N_0=1.765±0.002;N_e=1.758±0.002;R_0=7.7%;R_e=7.6% at λ=589nm.

The CA_6 crystallized from calcined bauxite has been investigated by means of chemi-cal analysis,optical microscope,XRD and SEM. From the chemical composition, it is foundthat,in spite of the presence of more CaO compared with the theoretical value and of smallamount of oxides of Fe and Ti in solid solution with CA_6, the optical constants of theCA_6 mixed crystal, however,are not effected, i.e., (一)2V=0; N_0=1.765±0.002;N_e=1.758±0.002;R_0=7.7%;R_e=7.6% at λ=589nm. SEM shows that, the CA_6 appears as parallel crystalstock of hexagonal tablets on the(001) face. The result of XRD is in good agreementwith 7-85 of X-ray powder data file of ASTM. The microhardness of CA_6 can be distin-guished from those of corundum,its HV (001) being 1630±170kg/mm~2, and that on the face⊥(001) face is 1110±140kg/mm~2.

本工作对煅烧矾土中析出的CA_6做了化学分析、光学显微镜、X射线和扫描电镜研究。由化学组成可知,尽管在CA_6中固溶有比理论值为高的CaO和少量铁、钛氧化物,尚不致明显影响其光学常数。测定结果为:(一)2V=0,N_0=1.765±0.002;N_e=1.758±0.002;R_0=7.7%;R_e=7.6%。扫描电镜形貌观察表明;CA_6乃是六方片体,沿(001)面的平行连晶。X射线分析结果表明,同ASTM7-85卡片所示数据十分一致。显微硬度显著地低于刚玉,在(001)面上测得结果为1630±170kg/mm~2。

The problem expounds in this study has heen discussed for a long time. This paper deals with the wear mechanism of the impact plate of fon shaped coal-mill φ 1070/291 produced by Wuhan factory 3551 and the problem to enhonce its wear resistance. The wear conditions at different spots of the impact plate are investigated by using a scanning electronic microscope. It is shown that the wear essence of the impact plate is that at the inlet and in the middle, impact wear predominates. It means that the running off metal at the impact plate surface is caused by the attack of coal grains, which results in impact hollows. Subsequently, the coal grains press the metal surface to form turn over cortices. As a result of repeated impact of a great number of coal grains, the turn over cortices form themselves into a numder of microrifts and at last, break away from the metal plate surface in the form of mill-chips. Yet at the outlet spot of the impact plate there is washout wear in addition to impact wear. At the some time wear experiment is also made for Almonite and some preliminary opinions are proposed.

提高风扇式磨煤机冲击板耐磨性是一个讨论已久的问题。本文对武汉3551厂的φ1070/291风扇磨冲击板磨损机理和提高耐磨性进行了研究,文中研究冲击板各部位磨损情况,通过扫描电镜对已磨损冲击板不同位置进行微观形貌观察得出,冲击板磨损实质是:在进口端和中间部位,是以撞击磨损为主。即冲击扳表而金属的流失是由煤粒撞击金属表面,形成撞击坑,并推挤金属形成翻皮,在大量煤粒多次撞击下翻皮形成许多微观裂纹,最后形成磨屑脱离金属板面。而在冲击板出口测,除撞击磨损外,还存在冲刷磨损。本文在分析磨损机理的基础上,还对阿尔玛铸铁进行了试验,并提出一些初步看法。

The influence of the final annealing on the microstructure of the two kinds of Al foil for electrolytic capacitor was studied. The analysis of the relation among microstructure, etch morphology and specific capacitance was made. The experimental results showed that in the annealing condition the recrystallization texture has an important influence on the capacitance of etched Al foil. The specific capacitance increases with the increase of the component of cubic texture. Through observation on the etched morphology of Al foil, it was confirmed that the etching process of Al foil for electrolytic capacitor in a solution containing Cl~- has an evident crystallographic feature. In the <001> direc- tions the etch rate is the most rapid. In accordance with this crystallogra- phic etch feature, the influence of cubic texture on the etch morphology and specific capacitance of Al anode foil was interpreted.

本文研究了最终退火对两种电容铝箔组织结构的影响,分析了组织结构、腐蚀坑形貌和比电容之间的关系。实验表明:在退火条件下,再结晶织构对腐蚀铝箔的电容量有重要影响。立方织构含量增加,比电容提高。通过对铝箔腐蚀形貌的观察证实:电容铝箔在含有氯离子溶液中的腐蚀具有明显的结晶学特征,在<001>方向具有最快的腐蚀速度。根据这种特征解释了立方织构对腐蚀形貌和比电容的影响。
