Improving tribological performance of CrN coatings in seawater by structure design

Taguchi analysis of single layer CrN coatings on AISI 304 Stainless Steel to study its erosive corrosive wear behaviour

“…Out of these factors, impact velocity was considered as the most significant factor for the saline slurry erosion of the uncoated 304 steel samples and erodent discharge is the least significant factor in the case of slurry erosion rate for uncoated 304 steel. This result was in agreement with Gautam et al [19] who obtained impact velocity (79.85%) as the most significant factor in case of uncoated granite powder reinforced composites. Therefore, from both the Table 4 and 5 it can be seen that for uncoated sample impact velocity has most significant effect on erosion rate whereas it has least significant effect for CrN coated AISI 304 Stainless Steel.…”

Erosive Corrosive Wear Performance of Single Layer CrN Coatings on AISI 304 Stainless Steel in Sea Water Centrifugal Pumps using Steady State Analysis

“…It was further revealed from Figure 3 that the increase in coating thickness led to decrease in wear rate. An observation similar to this for steady state analysis was made by Patnaik et al [19] while working on chromium nitride coated aluminum alloys which were reinforced by varying percentage of granite. Rajahrama et al performed erosive corrosive test on stainless steel (SS316L), Carbon steel (AISI 1020) and nickel-aluminium-bronze (NAB) and found that increasing the velocity and sand concentration produced higher mass loss rates [20].…”

Microstructural Evolution in Chroming Coatings Friction Pairs under Dry Sliding Test Conditions

“…How the chroming coatings protect the substrate material interests both materials academic and technological communities [1][2][3][4][5]. Literature rarely reports the systematic study on the application of chroming coatings on carbon steel, the most important material for mechanical components and their tribological performance evaluation [6]. A reasonable database is provided for the further application of chromeplating coating in tool steel engineering; it is worthwhile to investigate the friction and wear behaviors of chroming coatings and the substrate materials [7].…”
