ESTABLISHING EMPIRICAL RELATIONSHIPS TO PREDICT POROSITY LEVEL AND CORROSION RATE OF ATMOSPHERIC PLASMA-SPRAYED ALUMINA COATINGS ON AZ31B MAGNESIUM ALLOY

Plasma sprayed ceramic coatings are successfully used in many industrial applications, where high wear and corrosion resistance with thermal insulation are required.In this work, empirical relationships were developed to predict the porosity and raspberry hershey kisses corrosion rate of alumina coatings by incorporating independently controllable

The prosperous and decent to need of both primary and secondary necessaries life are absolutely needed by every family.So they endeavor to increase their abilities to obtain subsist prosperity by entrepreneurship, as handicraft businesses, palm broom, that made by people in Krajan Hamlet, Kanigoro Village, modbiv Pagelaran District, Malang Regency.

In this case study we investigate the source region of whistler-mode chorus located close to the geomagnetic equator at a radial distance of 4.4 Earth radii.We use measurements from the four Cluster spacecraft at separations of less than a few hundreds of km, recorded during the geomagnetic storm of 18 April 2002.The waveforms of the electric field
