Aluminum addition effect to the resistance of the Ni-resist alloy cast iron to abrasion wear
Keywords:
aluminum, alloying element, Ni-Resist alloy, resistance to wear, intermetallic compounds, particle precipitation, alloyed ironAbstract
The objective of this investigation is to increase the resistance toabrasion of the NI-Resist cast iron alloy through particle precipitation while maintaining chemical stability unchanged by adding aluminum asintermetallic compound inducer. This contributes to the formation orprecipitation of homogenous particles. Ni-Resist alloy samples types 2and 3 were used maintaining nickel percent unchanged while varying thealuminum content. Aging thermal treatment was applied to induce theparticles. The results indicated that the addition of aluminum as analloying element to the Ni-Resist alloy increases the resistance to wearthrough particle precipitation due to its capacity as an intermetallic compound inducer. 0.5% aluminum addition produced the best results.Downloads
