Fabrication of bioglass infiltrated Al2O3–(m-ZrO2) composites

Abstract

Using 80 vol.% of poly methyl methacrylate (PMMA) as a pore-forming agent to obtain interconnected porous bodies, porous Al(2)O(3)-(m-ZrO(2)) bodies were successfully fabricated. The pores were about 200 microm in diameter and were homogeneously dispersed in the Al(2)O(3)-25 vol.% (m-ZrO(2)) matrix. To obtain Al(2)O(3)-(m-ZrO(2))/bioglass composites, the molten bioglass was infiltrated into porous Al(2)O(3)-(m-ZrO(2)) bodies at 1400 degrees C. The material properties of the Al(2)O(3)-(m-ZrO(2))/bioglass composites, such as relative density, hardness, compressive strength, fracture toughness and elastic modulus were investigated.

Stacked Bioglass/TiO2 nanocoatings on titanium substrate for enhanced osseointegration and its electrochemical corrosion studies

“…Even though Bioglass 45S5 has superior biocompatible properties it has poor mechanical properties and hence it could not be used for high stress applications like hip and knee joint prostheses. To overcome such drawbacks of Bioglass, bioceramics/metal oxide or bioceramics/metal combinations are preferred [15,16]. Such composites are expected to have improved mechanical and chemical properties compared to pure bioceramics.…”

“…The greatest advantages for EPD are less process time, perfect coating, inexpensive and also the possibility to obtain complex shapes [19]. Usually a trial and error approach is done elsewhere for obtaining the coating, but it is very tedious and less repeatability [16]. In our present work, we focused on "Design of Experiments (DOE)" for obtaining the optimization conditions for Bioglass/TiO 2 nanocomposites coatings obtained using the EPD technique [20].…”

Preparation and characterization of polyurethane–organoclay nanocomposites

“…In recent years, much attention has been focused on PU-clay nanocomposites, which represent greatly improved performance properties compared to the pristine PU [23][24][25][26][27][28][29][30][31][32][33]. However; there also exist some disadvantages concerning with thermal stability and solvent resistance properties.…”

〈110〉{111} dislocation core properties in L12 Al3 Sc and Al3 Mg based on the Peierls-Nabarro model

“…1 Introduction As lightweight structural materials with high specific strength and good castability, Al-Mg alloys have been applied extensively in the aerospace, automotive, and microelectronic industries [1,2]. However, their applications are still restrained due to limited mechanical properties, especially the low fracture strength [3,4].…”
