Uticaj uslova termomehaničke prerade na mehaničke osobine i električnu provodljivost PdNi5 legure
Main Article Content
Abstract
Ovaj rad obuhvata eksperimentalna i analitička ispitivanja uticaja termomehaničkog režima prerade na mehaničke osobine i električnu provodljivost PdNi5 legure, u obliku žice Ø 0,15 mm, za izradu katalizatora–hvatača. Ispitivanja pokazuju da mehaničke osobine i električna provodljivost zavise od primenjenog režima termomehaničke prerade. Poznavanje zavisnosti uticaja parametara termomehaničkog režima prerade na ove osobine omogućava proizvodnju PdNi5 legure zahtevanih karakteristika za primenu u procesu katalitičke oksidacije amonijaka, odnosno rešavanje problema gubitka platinskih metala, pre svega platine. Rezultati analitičkog ispitivanja uticaja termomehaničkog režima prerade softverskim paketom SPSS na zateznu čvrstoću, izduženje i električnu provodljivost PdNi5 legure u obliku žice Ø 0,15 mm pokazali su da se primenom linearne regresione analize na adekvatan način mogu opisati i analizirati međusobni uticaji izabranih parametara termomehaničke obrade na mehaničke osobine i električnu provodljivost PdNi5 legure. Dobijeni rezultati ukazuju da se zatezna čvrstoća i električna provodljivost neznatno menjaju sa promenom temperature i vremena žarenja dok izduženje značajno raste sa povećanjem vremena žarenja.
