Foundry Coatings - Review
Journal Title: Journal of Materials and Engineering - Year 2023, Vol 1, Issue 1
Abstract
The main purpose of this publication is to present the founding stages of the foundry industry and its fundamental importance to the engineering sector. The second focus is to examine the technology of casting in sand molds and more specifically those based on no-bake process(chemically hardening). The auxiliary materials used for the production of sand molds and their importance for the quality of the final part-casting are examined in detail. Special attention is paid to refractory coatings, and in particular those with graphite filler, because of their wide application. The main chemical parameters are presented and the need to study their geometric and tribological characteristics and their influence on the quality of manufactured castings is emphasized. Until now, the author of the publication has studied the micro hardness, roughness, friability and gas permeability of refractory coatings, for which parameters no previous information on similar tests has been found. The research carried out was financed under phd project No. 222ПД0005-05 – TU Sofia, Bulgaria.
