The electrical energy dissipated in one pulse is measured with a calorimetric method to be 80 mJ. From photographs detailed information on streamer structure is obtained. In a gap of 20 mm at a pulse voltage of 20 kV the average length of the streamer in tap water is 5 mm, in deionized water it is 11 mm. The number of streamers is higher in tap water. The propagation velocity of the streamers is determined using photomultipliers and is in the order of 10 6 m/s.","PeriodicalId":239347,"journal":{"name":"Proceedings of the International Thermal Plasma Processes Conference","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737508","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}

The evaporation time of zirconia was estimated to be 130 and 560 μs for spherical particles with radii of 6 and 12.5 μm, respectively. The plasma temperature in excess of 7000 K as inferred from spectroscopic measurements allows for the existence of zirconia vapour. Mie scattering of laser light yielded evidence that zirconia particles with a maximum diameter of 12 μm could be completely vaporised at a rate of 200 mg min −1 , if the hydrogen content of the argon–hydrogen plasma was sufficiently high.","PeriodicalId":239347,"journal":{"name":"Proceedings of the International Thermal Plasma Processes Conference","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126371573","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}

It was possible to obtain particles with alumina shells with a mean thickness of 2−4 μm. EDS analysis showed that, according to the detection limit, no alumina was imbedded in the steel core and reciprocally no steel was included in the alumina shell. The composite powder was then plasma sprayed using a PTF4 type plasma gun (nozzle internal diameter 7 mm) with the internal injection of the powder 3 mm upstream of the nozzle exit. The arc current was 500 A and plasma forming gas mixture was 53 slm Ar and 7 slm H2. The coatings were sprayed on cast iron samples (diameter: 25 mm, thickness: 5 mm) located on a rotating substrate holder (110 mm diameter). The plasma torch was moved parallel to the holder axis. The substrates were preheated with the plasma gun and their surface temperature was controlled by air jets monitored by an IR monochromatic pyrometer.
