Influence of microstructure and experimental parameters on the erosion–corrosion behavior of Al alloy composites

Influence of Material Hardness and Particle Velocity on Erosive Wear Rate

“…To reduce erosion wear of the components, wear resistant coatings are performed by using different methods such as weld overlay diffusion 7 , thermal spray 8,9 or HVOF (high velocity oxy fuel) spray method 10 . Many parameters are effective on erosive wear rate such as liquid type, solid particle impact angle, velocity and energy, size and shape, solid particles concentration, hardness and toughness of the material [7][8][9][10][11][12][13] . Researchers have investigated the effect of different parameters on erosion wear.…”

Corrosion Behavior of Alumina Reinforced Aluminium (6063) Metal Matrix Composites

“…Stir casting was selected because it is a cheap and efficient process route which also has the advantage of adaptability to the use of improvised facilities [7 -9]. The investigation is intended to assess the corrosion resistance of the alumina reinforced Al (6063) matrix composites in acidic, salt water, and basic environments which are representative of typical service / industrial processing atmospheres [10].…”

Erosive wear response of SiCp reinforced aluminium based metal matrix composite: Effects of test environments

“…This is due to the fact that with the increase in rotational speed, the kinetic energy of the impinging particle increases and hence this increases the wear rate with the rotational speed. At a higher speed, the sand particles simply slide off instead of making any sensible impact as they do not have enough time to make an effective impact due to the decrement in mobility of the sand particles [16]. This led to the reduction in volume loss at a higher speed.…”

“…The severity of the erosive/abrasive attack depends on the energy of the erodent, number of impacts made, number of impingement particles in the given volume of the slurry, angle of impact, shape and size of the erodent, speed of the impingement particles etc. [16] and the corrosivity of any medium as a function of its pH and anodic ion concentration [38]. …”

“…In another study, Yu et al [15] delineate that the interfacial attack as well as corrosion is minimised due to the formation of a nobble intermetallic layer in the interface. Saraswathi et al [16] investigated the combined influence of material related parameters such as the matrix microstructure, reinforcement volume fraction as well as experimental parameters such as sand content and speed on the erosion/corrosion behaviour of AMCs in three different environment types, namely marine, synthetic mine water and basic media. Their study concluded that AMCs exhibited better wear resistance than the base alloy in NaCl and acidic media irrespective of the sand content and speed.…”
