The focus of manufacturing for tungsten carbide applications often demands a smooth surface quality as the result of the Electric Discharge Machine (EDM) die-sinking process, especially in the manufacture of die and mold with tungsten carbide material pro... see more

Flexible n-type tungsten carbide/polylactic acid (WC/PLA) composites were fabricated by additive manufacturing and their thermoelectric properties were investigated. The preparation of an n-type polymer-based thermoelectric composite with good stability i... see more

Polycrystalline diamond compact (PDC) bits are commonly used drill bits in the petroleum drilling industry. Cracks often occur on the surface of a bit, which may result in the unexpected suspension of the drilling operation, or even accidents. Therefore, ... see more

In this paper a self-developed polycrystalline diamond coating was done on tungsten carbide (WC) tool insets by using simple thermal chemical vapor deposition technique. The growth of these diamond films has been carried out at ~900 ºC temperature. The as... see more

Titanium coated tungsten carbide (Ti-WC) drill bit was used for drilling on the carbon-carbon composites laminates. The drilling speed was varied between 1000 to 3000 rpm with different feed rate of the drill. With respect to the time, the thrust force ex... see more

X-ray diffraction phase analysis of samples performed on a DRON-6 diffractometer has shown that the processes of CaWO4 transition to WC and W2C had the highest probability in the temperature range of 1,173–1,473 K. The end-product CaWO4, thermally treated... see more

Introduction: Preservation of the enamel surface during the removal of orthodontic appliance is an essential aspect for clinicians. However, various therapeutic measures can affect the enamel surface. The objective of the research is to evaluate the rough... see more

The ultra-short pulse laser has attracted attention as an advanced tool for functionalizing surface topography, since it has high accuracy and results in little damage. In a previous study, some innovative patterns were introduced on cemented carbide surf... see more

Cemented carbides are outstanding engineering materials widely used in quite demanding material removal applications. In this study, laser surface texturing is implemented for enhancing, at the surface level, the intrinsic bulk-like tribological performan... see more
