Cyclic pressing is a new kind of densification processing, which is introduced to densify as - deposited ring of al - 20 % si / sicp. this paper includes the densification result and rule of this technics. the research shows that this technics can be successfully used to densify spray - forming porous material and can be availably adopted to improve mechanical performance and microstructure. this technics is characterized by simple equipment 、 small expense and flexible process, and these characters will make it come true to producing spray - deposited rings less costly
本文採用一種新型緻密化工藝?楔壓工藝?對噴射沉積al - 20 % si / sicp大環進行了緻密化加工，採用密度硬度分佈、抗拉強度變化和檢測顯微組織變化的實驗研究方法對其緻密化效果及該工藝規律進行了研究，通過研究表明了楔壓工藝可以成功地用來緻密化噴射沉積多孔材料，該工藝有效地提高了噴射沉積大環件的緻密度和抗拉強度並改善了組織。 -

Compared with those of as - sprayed ring, hardness and tension strength of area near processing face are increased by 45 % and 40 % respectively. friction mechanical performance of the ring is improved at large extent, and especially the wearing amount is merely 13 % of as - sprayed rings. after dual - direction cyclic pressing, the pore - closed state and the distributing of density and hardness are nearly identical in every part of ring. the friction mechanical property is close to that of single - direction - cyclic - press ring
靠近壓力加工面部位，硬度較沉積坯提高了45 % ，拉伸強度較沉積坯提高了40 % 。雙向楔壓后孔洞閉合、密度硬度分佈都比較均勻。單向楔壓后，用壓力加工面作為摩擦面， al - 20 % si / sicp復合材料的摩擦磨損性能得到大幅度提高，尤其磨損量為楔壓前的13 % 。 -
( 2 ) for the cyclic pressing technics, the thickness of densified layer of ring was studied, and the rules which the technics must follow had been investigated, and the influence of parameter on densification results had also been investigated. according to the theory of rolling, the conclusion of thickness of densification layer had been drawn for the dual - direction cyclic pressing. the term that decreased height of one stage and distance of one step advancing had been researched

As they stepped on to the doorstones, and halted to take a last look at the moon - or, more correctly, at each other by her light - i felt irresistibly impelled to escape them again ; and, pressing a remembrance into the hand of mrs dean, and disregarding her expostulations at my rudeness, i vanished through the kitchen as they opened the house - door ; and so should have confirmed joseph in his opinion of his fellow - servant s gay indiscretions, had he not fortunately recognized me for a respectable character by the sweet ring of a sovereign at his feet
