Microstructural and Wear Properties of Annealed Medium Carbon Steel Plate (EN8) Cladded with Martensitic Stainless Steel (AISI410)

Abstract

Limited work on the wear properties of martensitic stainless-steel weld clads initiated this work which included investigations on microstructural and wear properties of cladded AISI 410 (filler wire)/EN 8 plates (substrate). Three layers of martensitic stainless steel (AISI 410) were deposited using metal inert gas (MIG) welding on medium carbon steel (EN 8) achieving a 51.5 ± 2.35 HRC of top layer. The elemental and phase fractions of the cladded layers indicated 98% martensite phase and retained austenite (2%). About 40% dilution was observed between EN 8 and the first weld layer. The results of tests carried out on pin on disc tribometer revealed an enhancement of anti-wear life of the martensitic weld cladded EN 8 by three times that of uncladded EN 8. The uncladded EN 8 plate suffered severe damage and high wear, leading to its failure at 478 s. The failure of the uncladded EN 8 sample was identified by the occurrence of high vibration of the pin on disc tribometer which ultimately stopped the tribometer. On the other hand, the cladded EN 8 sample continued running for 3600 s, exhibiting normal wear. After the tribo test, the surfaces of the pins of both cladded and uncladded EN 8 were analyzed using scanning electron microscope (SEM) and 3D profilometer. The surface characterization of tribo pairs indicated ploughing and galling to be the primary wear mechanisms. The average grain size of top and middle layer was in the range of 2–3.5 µm, while the base metal showed 5.02 µm mean grain size, resulting in higher hardness of clad layers than base metal, also favoring better wear resistance of the cladded EN 8 samples as compared to uncladded EN 8 samples.

Effect of Electroless Nickel Coating on Wear Rate of EN8 Steel

“…When compared with uncladded EN8 samples, the coated samples always show better wear resistance as found in the present work and also reported in several literature [14]. The solution to the severe wear can be achieved through a controlled heat treatment by inducing crystallization of amorphous nickel to Ni 3 P [15]. Ni-P coated samples tested under brine environment [16], also confirms the present trend of frictional parameters reported in the present work.…”

Mapping Acoustic Frictional Properties of Self-Lubricating Epoxy-Coated Bearing Steel with Acoustic Emissions during Friction Test

“…The surface morphology and surface roughness of the worn surface were analyzed using a non-contact surface roughness tester (make: Taylor Hobson, model: Talysurf CCI Lite, Leicester, UK). The specific wear rate of the coated bars was calculated using the Archard equation [50].…”

Resistance of Heterogeneous Metal Compositions to Fracture under Dynamic and Cyclic Loads

“…It should be noted that to date, the influence of the characteristics and properties of homogeneous (monolithic) layers and their combinations on the macroscopic parameters of the entire composite, its properties and performance as a whole has not been established. There are no studies identifying the contribution of the transition zone, which, for example, when using surfacing to produce layered materials, has fairly extended dimensions [21]. In each specific case, it is not clear what materials and what ratio of characteristics of adjacent layers are necessary to obtain the desired properties of the composite layer.…”
