Mechanical Properties and Linear Shrinkage of Resins Reinforced with Micro Hydroxyapatite for Dental Restoration  185 Views
In this study, hydroxyaptite (HA) Ca10 (PO4)6(OH)2 nano size has been synthesized from waste materials (egg shell and fish bone ) and then mixed with resin composite in order to measure the mechanical properties and linear shrinkage of composite materials designed for dental restoration.
Study the Properties of Microplasma Oxidation Coatings (MPO) Deposited on Aluminum Alloy under modified Conditions  170 Views
The aim of the present research is to study the properties of MPO coatings deposited on aluminum alloys under modified conditions so as to improve the hardness of MPO coatings by reducing the porosity which is the most complex phenomenon can affect the distribution and measurements of hardness, and wear rates of the coatings.
Improvement of Surface and Properties of Cast Stone by Coating and Palm leaf Sheath Fiber Wastes  145 Views
The present study is an attempt in improving the mechanical and antibacterial surface properties of the cast stone by self compacting concrete method by using different volume fractions of palm leaf sheath fibers (PLSF) (0.1, 0.2 and 0.3) % and coated with nano Zno/Epoxy coating using doctor blade method , at different Zno ratios (0.5 ,1 and 1.5) %.
Glazing and Coloring of Cellular Concrete Blocks  135 Views
Thermostone is one of the important materials which have been spraying glazed using different glass mixtures based on alkaline (A5), lead glasses (A4) and their composition at different glass/water (G/W) ratios using a special holder have been designed to keep the glazing on top of thermostone and thereby, protect the other surfaces from damage
STUDY ON AL2O3 DUPLEX COATINGS DEPOSITED BY NEW MICRO-ARC OXIDATION (MAO) PROCESS USING NATURAL ADDITIVES OF RICE HUSHES ASH (RHA) AND PORCELANITE ROCKS OF PRE-ANODIZED 6061 AL ALLOYS  113 Views
In this study, pre anodized Al 6061 alloy was coated with protective ceramic coatings using micro- arc oxidation process (MAO).
Effects of Rice husks ash addition on alumina layers deposited on 2024 aluminum alloys by micro-arc oxidation(MAO).  114 Views
the aim of this study, formation of ceramic oxide coatings by the micro-arc oxidation (MAO) on 2024 aluminum alloy with rice husks ash containing electrolyte solution
Double- layer coatings for surface improvement of Al 6061alloys by anodizing and micro plasma oxidation process MPO using new hydroxyapatite and rock additives modified electrolytes  111 Views
In this work, duplex ceramic coatings were deposited on Al 6061 alloy, using anodizing and micro plasma process (MPO)
Effects of natural rock and nano-TiO2 additives on Al2O3 layer formed on Al alloy by Micro Arc Oxidation (MAO)   103 Views
ceramic coatings on Al alloys were prepared via Micro Arc Oxidation process using natural rock additive (10g/l fired and unfired porcelanite), and (2.4g/l) nano-TiO2.
