Oerlikon Metco’s titanium and titanium alloy powders produce coatings having a range of characteristics not found in any other thermal spray powder materials. The coatings are light in weight with high strength-to-weight ratio and resistant to most corrosives. Titanium readily combines with other metals to form useful alloys. Owing to these suitable mechanochemical properties, pure titanium and titanium alloy powders can be employed in a number of applications via chemical, powder metallurgy and thermal spray processes.

Thermal spray coatings of titanium-based materials are commonly used in medical applications where biologic compatibility is required. Additionally, these coatings may also be used as a potential bond coat for hydroxylapatite coatings that are often used as a top-coat on biomedical implants. Titanium powders may also be used to produce dense, corrosion resistant coatings. Titanium powders have strong affinity and reactivity with oxygen, hydrogen and nitrogen at high temperatures. Most of the thermal spray coatings from these powders are produced under controlled atmosphere conditions (low pressure or soft vacuum).

The materials Metco 4010A, Metco 4010B, Metco 4010C, Metco 4010D and Metco 4010E of this material family differ primarily in their particle size distribution and are all manufactured via HDH.

Handling recommendations

Store in the original container in a dry location; Open containers should be stored in a drying oven below 38°C (100 °F) to prevent moisture pickup; Tumble contents prior to use to prevent material segregation.

Use coarser pure titanium powders such as Metco 4010E, Metco 4010D or Metco 4010B and titanium alloy powders such as Metco 4030A or Metco 4030B to produce coatings with very high surface roughness and porosity. These types of coatings are often desirable for biomedical implant applications because the porous structure is believed to promote bone growth onto the implants. Use fine powders such as Metco 4010C to produce relatively smooth and dense coatings. These types of coatings may be suitable for applications requiring corrosion resistance. Grade 4 titanium powders are recommended for use in biomedical applications. For some biomedical applications, layers of both the fine and the coarse powders may be applied serving different functions. HDH powder products are less expensive than atomized powder products.
