Investment castings often have surface impurities, and pieces of shell moulds can remain on the after sandblasting. Identification defects involves time-consuming manual inspections in working environments high noise poor air quality. To reduce labour costs increase health safety employees, automated optical inspection (AOI) combined with a deep learning framework based convolutional neural net...

Objective: To explore the mechanical properties, biological activity, and osteogenic ability of 3D printed TC4 titanium (Ti) alloy dental implants treated with surface modification. Methods: Dental 30% porosity were manufactured using selective laser melting (SLM) technology (group 3D), while traditional numerically-controlled machine tools (CNC) used to manufacture without SL). The then modifi...

Background and Aim: Fractured metal-ceramic restorations may be repaired with composite in some cases to postpone the fabrication of a new restoration. Knowledge about the bond strength can help predict the success rate of this treatment modality. The aim of this study was to assess the effect of two types of mechanical surface treatment of metal along with the use of different adhesive systems...

Logam baja merupakan material utama yang umum digunakan dalam industri hidromekanikal. Jenis logam banyak pada ini adalah karbon rendah, karena rendah memiliki keuletan tinggi dan mudah machining. Produk hidromekanikal dirancang dengan umur operasi selama 20 hingga 25 tahun. Salah satu faktor keselamatan wajib diperhatikan pertumbuhan korosi semua bagian struktur produk. Proses terjadinya tidak...

This study evaluated the effect of chemical and mechanical surface treatments for cast metal alloys on the bond strength of an indirect composite resin (Artglass) to commercially pure titanium (cpTi). Thirty cylindrical metal rods (3 mm diameter x 60 mm long) were cast in grade-1 cpTi and randomly assigned to 6 groups (n=5) according to the received surface treatment: sandblasting; chemical tre...

In this work, we performed comparative studies of the effect of surface preparation of Ti6Al4V and Ti6Al7Nb biomedical alloys and the influence of endothelial cells on their corrosion behaviour in PBS (Phosphate Buffered Saline). Two different methods of surface modification were applied - polishing and sandblasting. The polished Ti6Al7Nb alloy was found to have the best resistance against gene...
