Microstructure and osteoblast response of gradient bioceramic coating on titanium alloy fabricated by laser cladding

Recent advances in laser surface treatment of titanium alloys

“…In addition, changes are being studied in the composition of the powder that compensate for the loss of phosphorus during processing and prompt the formation of bioactive phases. [8][9][10] The result is an improved metallurgical bond with the substrate ͑Fig. 1͒ and a gradual increase in hardness that facilitates relaxation of tensions and osseointegration.…”

Microstructure analysis and wear behavior of titanium cermet femoral head with hard TiC layer

“…Titanium alloys are generally widely applied for dental and non-cemented orthopaedic implants due to their similar modulus to human bone, superior biocompatibility and corrosion resistance (Conforto et al, 2004;Niinomi, 2007;Zheng et al, 2006;Zeng et al, 2005;Zheng et al, 2008). However, a main limit of titanium alloys is their poor tribological behavior, characterized by high coefficients of friction, severe adhesive wear with a strong tendency to seizing and low abrasion resistance (Abkowitz et al, 2005;Ceschini et al, 2008).…”

Effect of CeO2 and Y2O3 on microstructure, bioactivity and degradability of laser cladding CaO–SiO2 coating on titanium alloy

“…In the biomedical field, laser cladding technique has been applied to produce bioactive coatings on Ti-6Al-4V alloy. Deng [24], Wang et al [11,25] and Zheng et al [26,27] on Ti-6Al-4V surface with calcium phosphate bio-ceramics by laser beam. Comesaña [2,28] produced bioactive glass coatings and calcium phosphate three-dimensional grafts by laser cladding.…”
