Description

504 208 2 Föreliggande uppfinning avser även legering med sådana tillsatser.
Det för sättet enligt uppfinningen använda pulvret erhålles på känt sätt genom atomisering av smält metall. Detta pulver placeras sedan i en metallkapsel som kan utformas så att den vid hetisostatpressningen erhållna produkten är färdig för användning. Kapseln kan avlägsnas genom kemisk eller mekanisk bearbetning, t ex betning eller svarvning. Ett annat sätt att ge den pulverprodukt som skall hetisostatpressas önskad form är metallformsprutning (eng. metal injection moulding, MIM), varigenom formas en s.k. grönkropp av metallpulver och binde- medel. Grönkroppen behandlas sedan genom sintring, varvid bindemedlet bränns bort. Denna metod är lämpad för tillverkning i serier, medan den ovan beskrivna metoden med metallkapslar är en enstyckstillverkning.
Det är lämpligt att före användning oxidera ytan hos produkten.
Härvid bildas på ytan ett skikt av aluminiumoxid, vilket i många fall även kan erhållas under drift, om denna innebär höga temperaturer och oxiderande atmosfär. Genom föroxidering kan emellertid skiktets egenskaper bättre kontrolleras och exempelvis ett tätare skikt uppnås än vad som annars erhålles. Även i icke oxiderande atmosfär har ett sådant skikt stor beständighet. Enligt uppfinningen framställda produkter har sålunda unika egenskaper vid användning i aggresiva atmosfärer, speciellt i uppkolande miljö.
