etallic biomaterials are used for a wide range of
implant applications where high and low cyclic
stresses occur concomitant with corrosive
effects associated with human body chemistry.
This makes enhanced surface properties of
implantable alloys crucial in medical device applications such as
artificial hip and knee implants that depend on well-engineered
biomaterials.
Applications have improved through the broad adoption of
materials, coating, processing methods, and designs. A Mayo
Clinic study released in 2014 showed that in 2010 there was a

combined total of 7.2 million Americans living with total knee
arthroplasty (TKA), and total hip arthroplasty (THA) implants.
Materials for TKA and THA typically include titanium alloys,
cobalt-chromium alloys, stainless steel alloys, polyethylene and
ceramics. Since the 1990s the dominant design for THA has
been a rough or porous coated titanium shell with an alumina
[ceramic] liner.1
Furthermore, dental implant applications, which have also
evolved substantially in past decades from additive manufacturing
(AM) of powder metals, have seen surface nitriding as a useful
technology to enhance biocompatibility.2
