“…The correlation between mass loss and electrochemical measurements was also investigated by Tan et al [15]. Aluminium bronze coatings are characterized by good fretting resistance in high-frequency conditions [16]. The slurry-erosion resistance of this type of coatings was investigated by Tan et al [17].…”

The plasma sprayed bronze coatings are widely used for repairing of plain bearing used in different applications. This type of coating was not deeply analyzed in state-of-art publications. In presented article we fill this gap in the case of plasma spraying process. The influence of power current (300/500/700A) and hydrogen flow (0/4/8 NLPM) on microstructure and thickness of aluminium bronze-polyester coating was investigated. The Thermico A60 plasma torch was used for thermal spray process of coating on flat carbon steel samples (grade S355). The Metco 604NS was sprayed with 20g/min powder feed rate. The obtained results showed the presence of local large pores formed by burning of polyester in plasma plume. This gap makes role of oil pockets in bearings. The obtained coatings were characterized by large deviation in thickness in range 200-350 micrometers. It might be concluded that in requires additional milling process after deposition.

“…Increasingly, aluminum bronze is being researched and considered for use as a wear-resistant material due to its outstanding friction and wear reduction properties. In some cases, aluminum bronze is applied to various alloys as a coating [ 21 , 22 ], while in other applications, it is used as a component of composites [ 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. In particular, more and more attention is being drawn to composite materials with intermetallic reinforcement based on aluminum bronze to be a kind of wear-resistant material.…”

Microstructures and Phases in Electron Beam Additively Manufactured Ti-Al-Mo-Z-V/CuAl9Mn2 Alloy

et al. 2023

Electron beam additive manufacturing from dissimilar metal wires was used to intermix 5, 10 and 15 vol.% of Ti-Al-Mo-Z-V titanium alloy with CuAl9Mn2 bronze on a stainless steel substrate. The resulting alloys were subjected to investigations into their microstructural, phase and mechanical characteristics. It was shown that different microstructures were formed in an alloy containing 5 vol.% titanium alloy, as well as others containing 10 and 15 vol.%. The first was characterized by structural components such as solid solution, eutectic intermetallic compound TiCu2Al and coarse grains of γ1-Al4Cu9. It had enhanced strength and demonstrated steady oxidation wear in sliding tests. The other two alloys also contained large flower-like Ti(Cu,Al)2 dendrites that appeared due to the thermal decomposition of γ1-Al4Cu9. This structural transformation resulted in catastrophic embrittlement of the composite and changing of wear mechanism from oxidative to abrasive.
