Corrosion Behavior of some Sintered CuNi Alloys – Preliminary Laboratory Data
The paper aims to discuss some aspects on corrosion behavior of specimens from sintered CuNi alloys (e.g. Cu90Ni10; Cu70Ni30). The above mentioned specimens were manufactured by dissimilar laboratory routes: from alloyed powders, from elementary powders and from mixtures consisting of Cu80Ni20 alloy and an alloying element. Research aims to establish the manufacturing parameters influence on sintered specimens characteristics (density, porosity, microstructure features) in order to correlate them with corrosion tests laboratory data. There were investigated the corrosion mechanisms in relation with macro- and microstructure properties of the sintered specimen surface. For comparison purposes, it is intended to extend the analysis to Cu60Ni40 and Cu80Ni20 sintered alloys.
