“…The adhesion strength of the porcelain coating to SLM-processed alloy was observed in nearly the same range of values. However, for such samples, the highest adhesion was found in the control subgroup (being 31.04 MPa), while for the sandblasted, bond-treated and treated in combined way samples, lower adhesion strength values of 27.91, 25.04, and 22.12 MPa, respectively, were obtained [26].…”

“…Previously, we demonstrated that for milled Ti6Al4V alloy, the highest adhesion strength of the porcelain was achieved in the second subgroup of sandblasted specimens (being 30.89 MPa), followed by subgroup 4 with combined treatment (27.96 MPa), while the control group and the bondtreated subgroup exhibited lower values of 25.04 and 17.63 MPa, respectively [26]. The adhesion strength of the porcelain coating to SLM-processed alloy was observed in nearly the same range of values.…”

“…1 b). After sandblasting, milled samples were reported to be characterized by a higher height of their Rz profile [10], which makes it difficult to obtain a thick oxide layer on their surface. This predetermines the larger adhesion strength of such a thin oxide layer to the metal, hence leading to failure mainly between the oxide layer and porcelain.…”

“…At the same time, each technological process is known to affect the roughness and morphology of treated surface differently. For instance, the surface roughness of SLM-processed Ti6Al4V alloy was shown to be several times higher than that of milled sample [8][9][10]. The surface morphology of milled samples is normally characterized by periodically repeated peaks and valleys [10], while non-melted and partially melted particles are observed on SLM-fabricated surfaces.…”

The present paper aimed at investigating the influence of surface treatment on the failure of porcelain coating on Ti6Al4V alloy fabricated by milling and selective laser melting (SLM). The titanium alloy surface was treated by three different ways: sandblasting, application of a layer of bonding agent and combined (sandblasting and subsequent bond layer). A coating of ultra-low fusing ceramic was fabricated on one surface of the samples. The adhesion of the porcelain to the titanium alloy was investigated by standard 3-point bending test and the failure of the coating was evaluated by optical microscopy. It was found that the type of surface treatment of the titanium alloy affects the failure mechanism of porcelain coating on its surface. In case of all samples, the fracture of the ceramics was observed to occur by a mixed adhesion-cohesion mechanism with a difference in the layer of adhesive or cohesive failures. These differences are greater for the milled alloy compared to its SLM-treated counterpart. In the milled sample, adhesive failure occurs along the metal/oxide layer interface and cohesion through the oxide layer. After sandblasting, both adhesion and cohesion fractures were observed between the oxide layer and the porcelain. In the bond-treated samples, adhesive and cohesive failures were found to occur mainly between the oxide layer and the bond. Most of the specimens treated in a combined way failed cohesively by cracking the ceramic coating. In the control and sandblasted subgroups of the SLM-processed alloy, the porcelain coating was destroyed through adhesive-cohesive route: adhesive along the metal/oxide layer interface, and cohesive through the porcelain. Ceramic fracture in the bond- and combined treated subgroups was observed to occur adhesively along the bond/porcelain interface, and cohesively through the bond and porcelain.

Additive manufacturing (AM), well-known as 3D printing, has revolutionized traditional manufacturing methods, particularly in the production of ceramic components. These techniques offer unique advantages and challenges in ceramic component production. Developing specific ceramic materials with AM improves the finished products' mechanical, thermal, and electrical characteristics. Integrating artificial intelligence and machine learning shows promise in improving process control and design optimization, spurring innovation and opening previously unimaginable possibilities, although problems such as material shrinkage, microstructural control, and surface polish remain crucial research areas. This review article presents a comprehensive overview of the advancements and applications of AM for ceramic pieces in the industrial sector. This study highlights the fundamental principles of AM, focusing on their difficulties and potential in ceramic fabrication. A comprehensive review of AM will deliver an understanding of its ability to alter industrial manufacturing and open the door to a new era of ceramic fabrication and applications.
