DAMORPHE has successfully developed several dissolvable alloys, fully and partially vitrified dissolvable bulk metallic glasses (BMGs) and dissolvable metal matrix composites (MMCs) with higher strength, elongation to failure & modulus, tailored dissolution, enhanced thermal stability, and with a significant production cost advantage over current offerings for O&G.
“Strengths in excess of 80-150 ksi”
Our dissolvable alloys / BMGs / MMCs not stemming from Magnesium (Mg) or Aluminum (Al) matrices, have yield strengths in excess of 80-150ksi, several times that of commercial offerings. They have a wide range of dissolution rates, or rates of corrosion (ROCs), and can be tailored according to customer requirements and well conditions. Mg dissolvable alloys typically suffer from poor thermal stability, that is loss of strength at elevated temperatures (35% strength de-rating at 350 °F). However, our dissolvable materials have enhanced thermal stability, with only 5% strength de-rating at 350 °F.
Current commercial offerings of dissolvable alloys, stemming from light metals, are sensitive to anion (ions with –ve charge) content in completions brines or produced formation fluids, resulting in numerous unpredictable failures of deployed products which call into question the reliability of dissolvable technology. Understanding these limitations and with a unique concept in material design, we have solved this industry shortcoming and created a series of anion insensitive dissolvables, triggered solely by temperature.
We are applying material innovation to design and produce high strength bioabsorbable materials with tailored strength, ductility, modulus, open cellular structure (porosity and permeability) enabling controlled drug delivery with embedded sensors and telemetry to communicate to external wearables for applications such as implants & medical devices.
Bioabsorbable, no H2 release
Abet controlled drug delivery
Metals such as titanium (Ti) and stainless steel (SS) are routinely used to repair bone fractures, holding together the broken pieces until the body has a chance to heal itself. Unless these metal fixtures are later removed, a painful and invasive process, patients will live with them for the rest of their lives, a potential source of future problems such as infection, damage to surrounding soft tissue due to stress shielding, or implant failure due to loosening.
Our biodegradable materials, primarily BMGs, are bioabsorbable without the risk of hydrogen evolution causing tissue damage or necrosis. They release Calcium (Ca2+) ions from built in precursors and abet controlled drug delivery, circumventing problems of stress shielding by making an implant that is stronger and lighter, and that has greater predictability of dissolution and control.
