Surface Laser Treatment of Cast Irons: A Review

نویسندگان

چکیده

Heat treatments are frequently used to modify the microstructure and mechanical properties of materials according requirements their applications. Laser surface treatment (LST) has become a relevant technique due high control parameters localization involved in modification. It allows for rapid transformation near surface, resulting minimal distortion workpiece bulk. LST encompasses, turn, laser melting hardening techniques. Many works devoted studying effects cast iron diverse spread several scientific communities. This work aims review main experimental aspects four cast-iron groups: gray (lamellar) iron, pearlitic ductile (nodular) austempered ferritic iron. The key parameters, such as power, scanning velocity, interaction time, on microstructure, composition, hardness, wear presented, discussed, overviewed. Finally, we highlight technological challenges regarding applied irons.

Microstructural characterization and kinetics modelization of vermicular cast irons

Several experimental techniques are used for phase identification and microstructure characterization of austempered vermicular cast irons (XRD, SEM, TEM and Mössbauer spectroscopy). Acicular structures were found to be composed by ferrite and austenite with average sizes compatible with those reported for bainitic ferrite in steels. An assessment of the free energy change involved in the auste...

Delamination Wear Mechanism in Gray Cast Irons

An investigation of the friction and sliding wear of gray cast iron against chromium plated cast irons was carried out on a newly constructed reciprocating friction and wear tester. The tests were the first to be done on the test rig under dry conditions and at the speed of 170 cm/min, and variable loads of 20-260 N for a duration of 15 min. to 3 hours. The gray cast iron surfaces worn by a pro...

Graphite Morphology’s Influence on Shot Peening Results in Cast Irons

The different shot peening responds of a grey cast iron (GI) with its flake graphite and a compacted cast iron (CGI) with its vermicular graphite was analyzed and compared in this paper. For peening using identical parameters, CGI showed a larger plastic deformation zone with higher subsurface compressive stresses than GI. Electron backscatter diffraction (EBSD) mapping and backscatter electron...
