Use of Additive Manufacturing by Localized Melting in the Recovery of Stamping Dies for the Ceramic Industry

Abstract

Among the Additive Manufacturing (AM) processes, the Wire Arc Additive Manufacturing (WAAM) technique is applied in the repair operations of metal parts and components. It is a fusion-based technology, known for its high deposition rate, low raw material waste, making it an economical manufacturing process that can be used for medium and large-sized parts. One of the main guidelines of WAAM is the repair of parts from production processes. In the ceramic sector, during the porcelain tile pressing stage, premature wear occurs in the liners that coat the matrix box cavity. This wear is associated with the use of highly abrasive atomized powder due to the content of feldspathic raw materials. The main objective of this study is to compare two different deposition path conditions for the hardfacing coating using UTP AF Dur 600 tubular wire via the WAAM process on test specimens with a base substrate made of SAE 1045 steel. The wear analysis of the specimens was conducted through the rubber wheel abrasion test in dry sand following the ASTM G65 standard, comparing their abrasion resistance. Thus, this work consolidates with a review of the state-of-the-art in Wire Arc Additive Manufacturing, enhanced with the concepts of the study object, evaluating its abrasive wear resistance based on the deposition path plan.
