Author:Tlotleng, Monnamme; Akinlabi, E; Shukla, M; Pityana, Sisa LDate:Feb 2014Coatings of commercial pure titanium (CP)-Ti and HAP bio-ceramic were synthesised on Ti-6Al-4V substrate using laser assisted cold spray (LACS) deposition technique. The LACS system comprised of 4.4 kW Nd:YAG laser system, AT-12000HPHV 5000PSI ...Read more
Author:Tlotleng, Monnamme; Akinlabi, E; Shukla, M; Pityana, Sisa LDate:Mar 2015Hydroxyapatite (HAP) is the most researched calcium phosphate material in the field of biomaterials to be used for bone re-engineering applications; given its attractive properties. Plasma spraying is the best available industrial method that ...Read more
Author:Tlotleng, Monnamme; Akinlabi, E; Shukla, M; Pityana, Sisa LDate:Feb 2014Bio-composite coatings of 20 wt.%, HAP and 80 wt.%, HAP were synthesized on Ti-6Al-4V substrates using LACS technique. The coatings were produced with a laser power of 2.5 kW, powder-laser spot trailing by 5 s. The coatings were analyzed for ...Read more
Author:Wepnener, I; Richter, W; Joubert, ADate:01 Sep 2010Strong, bioinert materials have always been the focus for bone replacement and repair. This practice has since moved towards materials that can mimic living tissue and aid the healing process (i.e. be replaced by natural bone); thus materials ...Read more
Author:Chetty, A; Wepener, I; Marei, MK; Kamary, YE; Moussa, RMDate:Aug 2012Hydroxyapatite (HA) has been extensively investigated and used in bone clinical application for more than four decades. The increasing interest in HA is due to its similar chemical composition to that of the inorganic component of natural ...Read more
Author:Yang, Y; Mkhonto, D; Cui, Q; Sahai, NDate:May 2011Bone sialoprotein (BSP) is an acidic, non-collagenous protein specific to bone proposed previously to promote hydroxyapatite (HAP) nucleation and modulate HAP nanocrystal growth. Specifically, two phosphorylated acidic amino acid sequences ...Read more
Author:Nilen, RWN; Richter, PWDate:Apr 2008Biphasic calcium phosphate ceramics (BCP) comprising a mix of non-resorbable hydroxyapatite (HA) and resorbable b-tricalcium phosphate (b-TCP) are particularly suitable materials for synthetic bone substitute applications. In this study, HA ...Read more
