Wear characteristics of AlCrN coating on AISI 410 steel by the ball-cratering test method

Abstract

Purpose In this study the microstructure and wear characteristics of Multilayer AlCrN coated AISI 410 stainless steel with the physical vapor deposition technique. Design/methodology/approach The friction and wear performance of the ML-AlCrN-coated AISI410 steel and uncoated AISI410 steel sliding against with high carbon steel were investigated by the ball cratering test at room temperature. The tribological characteristic of coated AISI410 steel was determined by applying constant sliding velocity of 0.3927 ms−1 and total sliding distance of 353.43 m over various normal loads of 2, 3 and 4 N. Findings The AlCrN-coated AISI410 steel showed excellent wear performance up to 4 N load. The uncoated AISI410 steel showed good to acceptable wear resistance up to 2 N load. The wear tracks and worn surface were examined by scanning electron microscopy with energy-dispersive X-ray spectroscopy (EDS) attachment for explaining the differences in wear mechanism. Originality/value The ability of coating to delay substrate oxidation, with an excellent wear resistance, was identified under different parameters on worn areas.

Effect of process parameters on the growth and wear resistance of CrAlN coating on silicon nitride surface

“…CrAlN coatings feature high hardness and wear resistance, making them widely used as wear-resistant coatings (Raja Abdullah et al , 2017). Preparing CrAlN solid lubricant coatings on the surface of Si 3 N 4 bearings can extend bearing service life (Cardoso et al , 2018; Prabakaran and Thambu, 2017). The wear resistance of the CrAlN coatings depends on the process parameters (Ling et al , 2022).…”

Tribological behaviour of TiAlN and AlCrN coatings on stainless steel

“…Martensitic stainless steels are used in numerous industrial applications, for instance, steam turbines, piston rings, blades, nozzles, where they are exposed to different wear and corrosion conditions which can cause failure or lead to frequent replacements of mechanical parts. 1 As a result of their high wear and corrosion resistance this type of steels is often employed for medical instruments, such as scalpels, scissors, valves and wearing parts of pumps, textile machine components and parts of machinery used in the food and packaging industry. In this case, steel parts are usually used with a small amount of lubrication or in dry running.…”

“…Additionally, the introduction of Aluminium into the crystallographic structure of nitrides has proven to increase oxidation resistance and hardness. 1,7,8 There are several publications about the tribological behaviour of AlCrN and TiAlN coatings. [5][6][7][8][9][10][11][12][13][14][15] However, the behaviour of these coatings deposited on martensitic stainless steels has not been extensively studied.…”

“…Since the tribological performance depends not only on the coating but also on the substrate microstructure and chemical composition, as well as the deposition method, it is important to consider the whole system: substrate-interphasecoating. 1,[16][17][18] In some previous publications about coated martensitic stainless steels, tests have been performed to evaluate their tribological behaviour under mild conditions (low load and pressure and short duration) or for specific applications like improving the durability of the cutting edge of certain tools. 1,[16][17][18] Taking into account that the industry is interested in estimating the service life of the treated parts or components, the aim of this work is to evaluate the tribological behaviour, adhesion and abrasion resistance of two commercial coatings under severe conditions, AlCrN and TiAlN, deposited by means of cathodic arc PVD by Oerlikon Balzers, Argentina.…”
