In-Depth Information
Electrophoretic
deposition
0.1-2.0 mm Uniform coating thickness; rapid
deposition rates; can coat complex
substrates
Difficult to produce crack-free coatings;
requires high sintering temperatures
Biomimetic
coating
< 30 μm
Low processing temperatures; can form
bonelike apatite; can coat complex shapes;
can incorporate bone growth stimulating
factors
Time consuming; requires replenishment and a
pH constancy of simulated body fluid
Hot isostatic
pressing
0.2-2.0 μm Produces dense coatings
Cannot coat complex substrates; high
temperature required; thermal expansion
mismatch; elastic property differences;
expensive; removal/interaction of
encapsulation material
Electrochemical
deposition
0.05-0.5 mm Uniform coating thickness; rapid
deposition rates; can coat complex
substrates; moderate temperature, low
cost
The coating/substrate bonding is not strong
enough
