“…However, they usually exhibit a poor sliding wear and cavitation erosion resistance which may result in material transfer, mechanical mixing and oxidation between sliding bodies and cavitation erosion in machinery such as hydro-turbines, pumps and valves. A possible solution to the above-mentioned wear problems is to coat the austenitic stainless steel parts by a layer of martensitic stainless steel with a good combination of corrosion resistance and high hardness and erosion resistance using laser cladding process [1][2][3][4].…”

The effect of cladding speed on phase constitution and properties of AISI 431 stainless steel laser deposited coatings Hemmati, I.; Ocelik, V.; De Hosson, J. Th. M. Take-down policy If you believe that this document breaches copyright please contact us providing details, and we will remove access to the work immediately and investigate your claim. Shorter processing time has given impetus to laser cladding technology and therefore in this research the AISI 431 martensitic stainless steel coatings are laser deposited at high cladding speeds, i.e. up to 117 mm/s. The analysis of phase constitution and functional properties of the coatings are performed by optical microscopy, Scanning Electron Microscopy (SEM), and hardness and sliding wear tests. The outcome of this research shows that an extreme refinement of the solidification structure will influence the phase constitution of the coatings by lowering the M s temperature and hence stabilizing the austenite which results in lower hardness values and increased wear rates. These results confirm that the structural refinement obtained by higher cladding speeds is not helpful for improving the hardness and wear properties of laser deposited martensitic stainless steel coatings.

“…Both low and high resistance to plastic deformation causes high maximal volume loss rate. Such relationship can explain reports of other authors that neither high nor low hardness of eroded material does not guarantee high cavitation erosion resistance [8,15].…”
