“…52 the Alloy 690, inhibition efficiency showed that the addition of Zn ions improves corrosion resistance at high pressure water environments. 53 However, the both corrosion studies showed that longtime inhibition, it may be caused long time inhibition efficiency due to zinc ions settling down and chromium scale may cause environment pollution. In our work green anticorrosion coating can have prolonged inhibition.…”

“…Furthermore, the translation zone grew mainly towards the compacted graphite iron. In contrast, the translation zone was brighter than the nickel-based coating, which is commonly known as diffusion transfer bright (DTB) [34,36]. The translation zone is often considered as a feature of metallurgical bonding [34,36].…”

“…In contrast, the translation zone was brighter than the nickel-based coating, which is commonly known as diffusion transfer bright (DTB) [34,36]. The translation zone is often considered as a feature of metallurgical bonding [34,36]. The top surface of the nickel-based coating became smooth, which seemed like the coatings' surfaces re-melted through oxyacetylene flame, as compared to the as-sprayed one.…”

“…Bergant et al [30,31] found that the adhesion between the coating and substrate was obviously enhanced after heat-treatment at 930 • C. Wen et al [32] applied the vacuum re-melting on a supersonic atmospheric plasma-sprayed NiCrMoY coating to improve the wear resistance with much lower wear weight loss than the as-sprayed one. Meanwhile, the surface roughness was reduced by the low melting component liquid phase filling into the pores and cracks with improved coating density [33][34][35][36]. Moreover, annealing in a vacuum system could avoid the decarburization of the sensitive engine parts using, for example, vermicular cast iron and steel.…”

Plasma-sprayed nickel-based self-fusion alloy coatings were annealed in a vacuum at 990, 1020 and 1050 °C for 20 min to increase the bonding between the compacted graphite cast iron substrate and coating, as well as the inner cohesion of the coatings. It was found that nickel and chromium diffused between nickel-based alloy coatings and compacted graphite cast iron substrate. A metallurgical translation zone with a thickness up to 1145 μm formed during the vacuum annealing, which resulted in an enhancement of the adhesion between the coating and substrate. The adhesion strength at room temperature was increased from the as-sprayed coating of 33.4 MPa to the annealed one of 163 MPa. Meanwhile, the adhesion strength at 500 °C reached 146 MPa. Conversely, the inner cohesion of the coating was improved with the particles’ interfaces healed after vacuum annealing. The micro-hardness of the annealed coatings was increased to 902 HV from the as-sprayed one of 578 HV.

“…NiCrBSi coatings straighten the homogeneity by reducing porosities and improve micro structural properties and tribological performance. These coatings are widely used in large industrial applications where high temperature wear, friction, corrosion and oxidation are required [3]. Based on this information, Demir et al [4] investigated the corrosion, friction and temperaturerelated brake attenuation characteristics by coating Al2O3-TiO2 by plasma spray method and NiCr-Cr3C2 coating with HVOF method on the cast iron disc.…”

 High bond strength was obtained between cast iron and NiCrBSi powder coated by flame spray technique.  Hardness of coated sample was found to be approximately three times higher than that of cast iron sample.  The wear rate of the coated sample was found to be lower than the wear rate that of the lamellar graphite cast iron.  The surface roughness of the coated sample was seven times lower than that of the cast iron sample.
