Particles larger than a component's internal clearances are not necessarily dangerous. Particles the same size as the internal clearance cause damage through friction. But the most dangerous particles in the long-term are those that are smaller than the component's internal clearances. Particles smaller than 5 microns are highly abrasive. If present in sufficient quantities, these invisible 'si...

in order to study the effects of silver nano particles, magnetic field in corporation with barium, lithium and micronutrient fertilizers on wheat, an experiment was conducted at research farm of razavi research and technology institute in 2008. experiment carried out with eigth treatments based on randomized complete block design with four replications. treatments were including (t1) magnetic f...

Finishing is a basic requirement for obtaining the required surface quality in production of various components used many industries. A relatively new finishing process, called magnetic abrasive finishing, complex shaped surfaces. This article presents latest developments polishing and describes results obtained by research scientists based on their experiments field polishing.

Being subjected to a high-pressure abrasive water jet, solid samples will experience an essential variation of both internal stress and physical characteristics, which is closely associated with the kinetic energy attached to the abrasive particles involved in the jet stream. Here, experiments were performed, with particular emphasis being placed on the kinetic energy attenuation and turbulent ...

Magnetic Abrasive Polishing (MAP) is a super-finishing process primarily used for polishing of nonmagnetic and hard materials like, ceramics and stainless steel. This paper deals with the detailed parametric study in polishing of stainless steel work surface. Statistically designed experiments based on Taguchi methods show that size-ratio, tool-work surface clearance, polishing speed, magnetic ...

In this article, the effect of parameters like working gap, work piece rotational speed and material removal mechanism(injection of the SiC Abrasive slurry and Al2O3, use of diamond paste as abrasive tool) in Magnetic Abrasive Finishing process using designing of experiments on the external surface of Cylindrical work pieces of Stainless steel AISI 440C to get minimum surf...

High quality, highly efficient finishing processes are required for difficult-to-machine materials. Magnetic abrasive (MAF) process is a method that can obtain high accuracy surface using fine magnetic particles and particles, but has poor efficiency. On the contrary, fixed polishing (FAP) material removal efficiency often cannot provide high-quality at nano-scale. Therefore, this work proposes...

The paper discusses the material removal process in refractory ceramics eroded by hydro-abrasive jets. In particular, bauxite, sintered magnesia, and magnesia chromite are eroded. The influence of abrasive particle velocity, local exposure time, abrasive mass-flow rate, and abrasive type is investigated. Erosion depth, specific erosion rate, and geometry of the generated cavities are measured a...
