We have deposited a series of WC–Co coatings by the high velocity oxy fuel (HVOF) process, using three different powders, and different spray conditions. The powders are a nanocrystalline (Nanocarb), a near-nanostructured powder (Infralloy) containing a proprietary additive aimed at retarding grain growth, and multimodal (mixed micro and nano) powder (Nanomyte). HVOF spray conditions were stoic...

Cubic silicon carbide (SiC) is an extremely hard and brittle material having unique blend of material properties which makes it suitable candidate for microelectromechanical systems and nanoelectromechanical systems applications. Although, SiC can be machined in ductile regime at nanoscale through single-point diamond turning process, the root cause of the ductile response of SiC has not been u...

The work is devoted to the problem of calculating surface roughness during magnetic abrasive processing. Cutting grains have random dimensional characteristics, are randomly located on tool, workpiece has an irregular profile. cutting parts partially remove chips and elastoplastically deform metal. Some vertices fall into marks formed by previous processing, some - from passage vertices. This p...

Abstract Steel shots are suitable for abrasive waterjet rock cutting and recycling because of the high hardness magnetic properties steel. This study evaluated rock-cutting performance characteristics steel shot waterjet. The responses garnet were compared at same conditions. used was collected particle-size changes before reuse, its re-evaluated. Overall, yielded improvements in range 30–50% w...

Abrasive water jet machining has been extensively used for cutting various materials. In particular, it applied difficult-to-cut materials, mostly metals, which are in manufacturing processes the fabrication industry. Due to its vast applications, in-depth comprehension of systems behind process is required determine effective usage. This paper presents a review progress recent trends regarding...
