You searched for subject:(Corrosion resistance AND soldering tendency of different materials in moltenAl Si Cu alloy were studied Hot working tool steel plasma nitrided steel andduplex layers with CrN TiAlN TiAlSiN AND CrAlN top coatings which wereproduced to various degree of surface roughness were covered by the study An ejection test was employed for investigation of the concerned phenomena The ejection test was improved in order to increase its accuracy AND thereliability of process simulation Samples were examined in both short andextended periods of contact 5 AND 20 min with liquid casting Castingsolidification was extended in order to intensify the corrosion effects Contraryto common findings it was found that the ejection force of the investigatedmaterials does NOT depend on their chemical composition For the coatedsamples a pronounced dependence of the ejection force on the surfaceroughness was found The ejection force increases with decrease in surfaceroughness All investigated coatings are prone to mechanical soldering by Al Si Cu alloy Still their corrosion resistance substantially exceeds the corrosionresistance of steel AND plasma nitrided layer Longer exposure of coatedsamples to cast alloy induced lower ejection forces which is a consequenceof coatings oxidation It was found that the investigated coatings are inert toliquid aluminium However the underlying material undergoes oxidation andcorrosion through coating growth defects The findings concerning the wearmechanisms of protective layers support further development of duplex layersintended for die casting tools protection ).
