Projekat

Mikromehanički kriterijumi oštećenja i loma (MPNTR - 174004)
Razvoj tehnologije izrade obloge i jezgra na bazi domaćih sirovina za proizvodnju specijalnih obloženih elektroda namenjenih za elektrolučno zavarivanje čelika (MPNTR - 34016)

Sažetak

Plazma je električno provodljiv gas koji sadrži jone, elektrone i neutralne molekule. Takvo stanje materije stvara se preko električnog pražnjenja i može da se održava u stabilnom stanju uvođenjem naizmenične ili jednosmerne struje. U radu je opisana struktura plazme, termodinamičke karakteristike i način stvaranja plazme koji omogućuju primenu plazme kao izvora energije za plazma sprej procese. Generalno, svi postojeći materijali u obliku praha mogu se plazmom deponovati kao prevlake na podlogama od različitih materijala. U plazma provodljivi gas na visokoj temperaturi uvode se čestice praha materijala koje se tope i ubrzavaju do podloge na kojoj formiraju prevlake. Masovna primena plazma sprej prevlaka u svim industrijskim oblastima je od posebnog značaja, jer se sa različitim kombinacijama površinskih slojeva može znatno povećati otpornost mašinskih delova na: habanje, abraziju, eroziju, kavitaciju, koroziju i otpornost na zamor na niskim i povišenim temperaturama, uz povećani resurs i pouzdanost rada delova u eksploataciji.
