Investigating the microstructure and hardness of 17-4PH steel and Stellite cladded by direct laser deposition process on 17-4PH steel substrate
The purpose of this research is to laser cladding of stellite6 and stainless steel 17-4PH powders on the substrate of stainless steel 17-4PH, and investigate its solidification microstructure. The results showed that the microstructure of the stellite6 cladding has a cobalt solid solution ground phase with an FCC structure and Cr7C3 and Cr23C6 carbides. Also, the values of the primary dendrit...

متن کاملImproving the Erosion Behavior of Inconel 625 Substrate by PTA-Deposited Stellite6/B4C Composite Cladding
The purpose of this study was to improve the erosion behavior of Inconel 625 alloy by plasma transferred arc-deposited stellite6/B4C composite cladding. For this purpose, 5 wt.% of boron carbide was added to the stellite6 clad. Phase analysis and microstructure evaluation were conducted by Optical Microscope, Field Emission Scanning Electron Microscope (FESEM), and Energy-dispersive Spectroscop...
متن کاملEffects of Different Levels of Boron on Microstructure and Hardness of CoCrFeNiAlxCu0.7Si0.1By High-Entropy Alloy Coatings by Laser Cladding
High-entropy alloys (HEAs) are novel solid solution strengthening metallic materials, some of which show attractive mechanical properties. This paper aims to reveal the effect of adding small atomic boron on the interstitial solid solution strengthening ability in the laser cladded CoCrFeNiAlxCu0.7Si0.1By (x = 0.3, x = 2.3, and 0.3 ≤ y ≤ 0.6) HEA coatings. The results show that laser rapid soli...
متن کاملEffect of Cladding Parameters on the Hardness of Bimetal Plates
R.Bęczkowski, Institute of Mechanical Technology, Czestochowa University of Technology, Poland Hardness is one of the components responsible for the resistance to wear. The development of new materials with hardness surface more than 65 HRC is possible with use welding technologies. High chromium cored wires belong to welding materials that are often used to cladding to protect surface. This ar...
