Deposition of a hydroxyapatite coating onto bioresorbable magnesium alloys to modulate corrosion performance in vitro

Magnesium alloys are being investigated for biomedical applications due their bioresorbable properties. However, use of magnesium as an implant material has been limited due to the rapid corrosion of the alloy in the presence of body fluid. This, in turn, results in the generation of a large amount of hydrogen gas and alkalisation of the local body fluid that can inhibit wound healing and ultimately lead to necrosis of the surrounding tissue. The application of coatings to the surface of magnesium is one potential solution to modulate the corrosion rate in vivo.

Hydroxyapatite (HA, Ca10(PO4)6(OH)2) is one potential coating candidate. It is already commonly used as a coating for orthopaedic applications. Thermal coating techniques, such as plasma spray, are the most widely used methods to deposit hydroxyapatite onto metal substrates. These high temperature techniques are unsuitable for magnesium alloys due to the low melting point of magnesium (≈ 600 °C).

Robotics in Space 

At the new ENBIO Space Technologies Centre, preparations have been completed to coat one of the largest parts since the completion of the Solar Orbiter Heatshield. This component is a satellite communications dish which is just over 1100 mm in diameter. Its dimensions highlight the versatility of the robots ENBIO use to perform CoBlast. To date we have coated a large variety of components including highly complex parts smaller than 50 mm and very fine components such as stents and foams.
 
The use of robotics allows the accurate and repeatable control of process parameters to ensure we can consistently deliver the desired surface treatment each time, on repeated customer parts. In conjunction with the scales of size already highlighted, robotics also allow careful manipulation to achieve predictable coating of both simple and complex geometries alike.
 
The use of robotics is complemented by real time process monitoring and data logging that ensures both in-house and customer requirements are met to produce the desired surface.
 
These systems allow us to take a customer part and design bespoke programming regardless how large or small, simple or complex. The programming can be designed and then verified with a computer simulation of the articulation of the robot arm, allowing the parts and relevant programming to be then transferred to the production team to transform the surface with complete confidence.
 
ENBIO have coated a wide variety of parts for the Space sector with our patented SolarBlack CoBlast surface treatment. Many of these have been used on the European Space Agency’s Solar Orbiter mission, as this unique SolarBlack surface allows these parts to withstand harsh conditions. From large dimensions to complex features, a new, custom fixture unit shown in the figure below, allows us to manipulate and rotate parts in the chamber in tandem with the robotic manoeuvres. The careful synchronisation of these machines allows us to give a bespoke solution to customer parts and seek out the optimal transformation of customer surfaces.

Titanium is a key metal and alloy component in the manufacturing scene. It is a tough, low density, high strength metal that possesses good heat transfer characteristics. It is twice as strong as Aluminium, 45% lighter than steel and does not become magnetised. These properties as well as its high melting point and corrosion resistance make it an important metal across the industrial manufacturing landscape. Its bio-compatibility also makes it ideal for medical device applications. To achieve optimal commercial use of these wonderful properties, the bond strength of Titanium parts joined to dissimilar materials often needs to be optimised. A popular bonding method is structural adhesive bonding.

A client recently approached ENBIO looking to apply SolarBlack to copper components. The aim was to increase the copper’s emissivity for use in a thermal radiator application. Through close collaboration ENBIO developed a new coating process using their needs as the design criteria. The client is now looking to use the coating immediately.

Enbio to create 12 jobs at new €1.5m ESA-funded centre in Clonmel!

Surface transformation company ENBIO is to create 12 new jobs at its newly opened €1.5m space technology centre in Clonmel, Co Tipperary, which has been funded by the European Space Agency (ESA).

The facility is ENBIO’s centre of excellence for the development and production of thermal management treatments or ‘sunscreen technology’ for satellites, spacecraft, and space related hardware.

It will enable ENBIO to produce the next generation of surface treatments to cope with the harsh conditions of Outer Space using its patented technology platform CoBlast.

#ENBIO had a very successful participation at the Paris #SpaceWeek 2015 in Orly, France. This business-to-business meeting opportunity has again proven to be an effective means of meeting new and old customers alike. Sales Manager Kevin O’Flynn was in attendance and he said “ENBIO have been hard at work pushing the limits of our technology platform, #CoBlast, and #PSW15 was a great opportunity to get direct customer feedback on our latest advances. Two developments are particularly exciting: we have produced new Zinc Phosphate primers that provide corrosion resistance and enhanced bonding between the metal and subsequent coatings or adhesives; and we have expanded our range of substrates for our SolarBlack thermal control coating to include copper. The customer feedback was very positive and validates our concerted R&D effort over the last year. Since the last Paris Space Week, we have taken our SolarBlack on titanium from TRL5 to TRL7, which is a huge leap in just one year. In total we have gone from TRL0 to TRL7 in just three and a half years, which is phenomenal. It really shows the strength of the research team in ENBIO.”

#UCD Engineers To Provide Protective Coating For Solar Orbiter Parts 

The surface treatment technology company ENBIO based at Belfield Campus, Nova UCD received a contract from the ESA (European Space Agency) in May 2014 to provide a patented surface treatment (CoBlast) to their Solar Orbiter Mission’s main heat shield. The contract was awarded after ENBIO’s surface treatment solution was subjected to extensive tests at #ESTEC (European Space Research and Technology Centre), the technical headquarters of ESA in the Netherlands. The approved #ENBIO solution makes use of new as well as old technologies. It incorporates a pigment that has been used in cave paintings 30,000 years ago into the company’s proprietary #CoBlast process.
