PM Anval Boosts Powder Production Thanks to improved atomization and screening techniques, Anval of Torsh~illa, Sweden, is increasing its production capacity for gas- atomized, pre-alloyed spray powders. The company is also issuing spray data sheets for standard grades, beginning with Anval 316, 80/20, 95/5 and 718, containing information on the powders and coatings, with recommended spray parameters for various types of equipment and also parameters for machining of the coatings. The following grades are now available from stock in Torsh/illa, in mesh sizes suitable for flame, plasma and HVOF spraying: Anval 420, 431,316, 254 SMO, 80/20, 95/5, NiMoA1, NiCrMoA1, 600, 625, 718 and C-276. Conference Reveals Considerable Interest in Spray Forming Some 220 people attended the 1st International Conference on Spray Forming, held in Swansea, UK, 15-17 September, 1990, proving that interest in the Osprey process is considerable. Highlights of some of the papers given at the meeting will be published in a future issue of MPR. Osprey was able to crown the conference success by announcing a new licensee for its process - Chaparral Steel of Dallas, Texas, USA. Reference Studies on Advanced Ceramics Seven studies have been published by Mitchell Market Reports: i) zirconia ii) boron carbide and boron nitride iii) aluminium nitride iv) titania and the titanates v) alumina vi) silicon nitride and the sialons; and vii) silicon carbide. Each of the studies is a comprehensive reference work including sections on: the different forms of the materials, methods of production, world production in the major countries, world trade, world consumption, end-uses, prices, activities by companies and research organizations, exchange rates and terms used.
