Sinter-bonding of Iron Based Compacts Containing P and Cu
Pieczonka Tadeusz,Kazior Jan 한국분말야금학회 2006 한국분말야금학회 학술대회논문집 Vol.2006 No.1
The sinter-bonding behavior of iron based powder mixtures was investigated. To produce the green compacts to be joined the following powders based on AB grade NC 100.24 plain iron powder were used: NC 100.24 as delivered, PNC 30, PNC 60 and NC 100.24 + 4%Cu powder mixtures. Dimensional behaviour of all those materials during the sintering cycle was monitored by dilatometry. Simple ring shaped specimens as the outer parts and cylindrical as the inner parts were pressed. The influence of parts' composition on joining strength was established. Diffusion of alloying elements: copper and phosphorous, across the bonding surface was controlled by metallography, SEM and microanalysis.
