“…A proper mechanical strength is necessary to maintain the shape against the stress during the surgical procedure and recovery [9][10][11]. However, the fast dissolution rate and the lower mechanical strength of wollastonite have severely hindered its clinical applications [12][13][14]. These problems can be solved by developing multiphase materials containing highly dissolvable phases and stable phases [15][16][17][18][19].…”

“…Titanium and its alloys are widely used in the aerospace [1,2], automobile [3], biomedical [4][5][6], energy industry [7], and military applications [8] due to their high strength, high-melting point, and good biocompatibility. However, poor corrosion and tribological properties are the disadvantages of these materials, and therefore they are usually used with protective coatings [9,10].…”

Titanium oxide (TiO 2 ) coatings were formed on titanium substrates in a sodium silicate (Na 2 SiO 3 ) aqueous solution, using plasma electrolytic oxidation method. The effects of duty ratio, frequency, and positive/ negative pulse proportion on the microstructure and phase compositions of the coatings were investigated. The coatings were mainly composed of anatase TiO 2 plus a little amount of rutile TiO 2 . The coatings obtained at the frequency range 900-2700 Hz, under a duty ratio of 20%, and a positive/negative pulse proportion of 3, showed the best quality in terms of density and adhesion. The effect of positive/negative pulse proportion was relatively small. However, continuous coating could not be obtained using the positive/negative pulse proportion of 1. Compared with that of bare titanium, the property of resistance to corrosion was obviously improved for the titanium with TiO 2 coating. The corrosion potential rose about 0.13 V and the corrosion current density decreased about one order of magnitude.

“…Thus, the implants need specifi c surface modifi cation in order to minimize the adverse effects. There are many methods for coating of metallic based implant materials, such as plasma spray coating [ 161 ], sputter coating [ 162 ], electron deposition [ 163 ], sol-gel route [ 164 , 165 ], electrolytic deposition [ 166 , 167 ], electrophoretic deposition [ 168 ], and cold spray [ 169 , 170 ].…”

Metallic materials have been used as biomedical implants for various parts of the human body for many decades. The physiological environment (body fl uid) is considered to be extremely corrosive to metallic surfaces; and corrosion is one of the major problems to the widespread use of the metals in the human body since the corrosion products can cause infections, local pain, swelling, and loosening of the implants. Recently, the most common corrosion-resistant metallic biomaterials are made of stainless steels and titanium and its alloys along with cobaltchromium-molybdenum alloys. It is well known that protective surface fi lms of the alloys play a key role in corrosion of the metallic implants. Key documents on the corrosion behavior of the metallic biomaterials in human body have been compiled under this chapter as a review. Keywords Metallic biomaterials • Corrosion • Physical body fl uid • Bioactive materials • Implant IntroductionThe main question is, "what is the most important property for a metallic biomaterial?" Clearly, the answer is biocompatibility . In addition, it is well known that corrosion is one of the major problems affecting the biocompatibility of orthopedic devices made of metals and alloys used as implants in the human body. Compared to other implants, metallic implants have excellent mechanical properties such as high elasticity, tensile strength, wear resistance, and machining.
