BMEN3318 - Introduction to Engineered Biomaterials

BMEN 3318 Introduction to Engineered Biomaterials (3 semester credit hours) The properties and processing of engineered materials used in biomedical devices are taught with an emphasis on the chemistry and structure-property relationships that control the mechanical, corrosion, and biocompatibility of materials used in acute and chronically implanted medical devices. Topics include the crystalline and amorphous states of metals, glasses and polymers, glass formation and bioactive glasses, mechanical properties, corrosion emphasizing passivity and galvanic corrosion, phase diagrams, macromolecular bonding and structure, and an introduction to material-tissue interactions related to the chemical stability of implants. The course also introduces basic material characterization techniques including uniaxial tensile tests, x-ray-diffraction, SEM/optical microscopy, potentiodynamic polarization, infrared spectroscopy, and differential scanning calorimetry. Materials covered include the stainless steels, CoCr-alloys, titanium alloys, polymers and oxide ceramics used in arthroplasty, and biodegradable polymers including drug-eluting polymers. Prerequisites or Corequisites: BMEN 1208 and (CHEM 1312 or CHEM 1301). (3-0) Y
