Some of the devices developed in the past years include mechanical, hydraulic, motor-driven and electromagnetic actuators. Existing most advanced system is an electromagnetic actuator using solenoids to activate engine valves. It, however, needs the current continuously in all operation period and has difficult starting problem resulting in low power efficiency. In this paper, we propose a novel electromagnetic valve drive system, and discuss the design, finite element analysis and construction of the experimental apparatus.","PeriodicalId":148739,"journal":{"name":"Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116246891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrolytic codeposition technique was adopted in the deposition of Ni-Fe-SiC composite coating on stainless steel substrate, using nickel alloyed with iron as the binder phase and SiC as dispersed particles. The morphology analysis indicated that the deposit with SiC nanoparticles is level and compact and the crystal-planes of the deposit are (111), (220) and (200). The resistivity of deposit is about 30×10−8 Ω·m. When the loading of Fe (wt.%) range from 10% to 50% in the deposit, the electrodeposit has a strong paramagnetism effect with the smallest coercivity of 2.75×10−2 A/m. The remanence shows a monotonic decrease with the increasing of iron content in deposit. It is proved that the electroformed Ni-Fe-SiC alloy has a good electromagnetic property and higher corrosion resistance (with the corrosion rate: 0.17mg/dm2 per hour in 2M HCl) than that of electroforming Ni-Fe alloy (with the corrosion rate: 0.23mg/dm2 per hour).","PeriodicalId":148739,"journal":{"name":"Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation","volume":"75 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116348287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
