Characterization, quantification, and isolation of aluminum oxide particles on grit blasted titanium aluminum alloy hip implants

Abstract

Remnants of grit blasting were found only on the surfaces; none were observed on cross-sections. We conclude that the microstructure of titanium aluminum alloy does not interfere with the identification and quantification of particles. Particles were identified on the filters by electron microscopy and X-ray microanalysis. Aluminum oxide on the surface of grit-blasted titanium aluminum alloy implants is, in fact, a residue of grit blasting.

The Condition of Ni-Cr Alloy Surface After Abrasive Blasting with Various Parameters

“…At the same time, the adhesive properties of surface increase ( Ref 1). Abrasive blasting is used in medicine and dentistry to increase the surface area of implants or dental restorations (Ref [2][3][4]. When creating ceramic crowns and prosthetic bridges, substructures made of dental alloys, such as cobalt-chromium or nickel-chromium alloy, are subjected to abrasive blasting (Al 2 O 3 , SiC) in order to ensure adequate conditions on the metal surface to filling with semiliquid ceramic during firing.…”

A cementless hip system with a new surface for osseous integration

“…Ten to 20 % of the surface of roughened cementless stems is contaminated with sharp particles from blasting media (alumina, glass, etc.) [6][7][8].…”

“…Standard surface-finishing processes use ceramic or glass particles to roughen the implant. In recent years, remnants of the blasting material (produced by gritblasting) have been reported on cementless fixation surfaces [6][7][8]. There have been reports of these particles remaining embedded on the finished product surface and being released into the joint, thus generating third-body wear [9,10].…”

Fabrication of strongly attached hydroxyapatite coating on titanium by hydrothermal treatment of Ti–Zn–PO4 coated titanium in CaCl2 solution

“…Titanium (Ti) and its alloys are widely used as metallic biomaterials for dental [1][2][3][4][5][6][7][8] and orthopedic [9][10][11][12][13][14][15][16] implants for their good biocompatibility. However, it is proven that large quantity of Ti ions are released when implanted into the body [17].…”
