Inverse Thermal Analysis as a Tool for Optimizing Concentrated Solar Energy Elaboration of Wear Resistant Surface Layers

Abstract

Concentrated Solar Energy (CSE) processing is considered a promising renewable energy source technique for elaborating thick, wear-resistant claddings onto metallic surfaces of large dimensions that are expected to operate in heavy duty applications, such as excavator shovels, mineral crushers, etc. However, the prediction of surface processing effects on the microstructure and the properties of the main construction base metal are of crucial importance, as they are commonly required in all surface modification techniques. Thus, the present study is focused on the inverse thermal analysis and parametric modeling of heat deposition associated with CSE surface processing of metals. In this preliminary attempt, experimental findings that concern the elaboration of TiC- and chromium carbide-reinforced clads onto common steel base metals were used to quantify the evaluation of the temperature histories within the volume of workpieces undergoing solar heating, where direct temperature measurements contain uncertainties and/or are not even possible. Results of prototype inverse thermal analyses of heat transfer in processed layer-substrate systems are presented, demonstrating the general aspects of a parametric model for thermal analysis and simulation.

Machinability and Tribological Performance of Advanced Alloys

“…The Special Issue "Machinability and Tribological Performance of Advanced Alloys" contains fifteen research articles [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], including one review paper [5]. The contents of this collection cover a wide spectrum of cross-disciplinary fields related to the machinability and tribological behaviour of materials with a variety of industrial applications.…”

“…The sulfurized fatty acid ester results in excellent anti-wear and anti-friction properties [11]. According to [14], a reverse thermal model and parametric modelling were applied to predict the temperature history of surface clads (carbide/steel systems) produced via a Concentrated Solar Energy surface treatment (CSE). This could result in the correlation between CSE processing parameters and the performance of created surface layers.…”
