Delphi Batch Process for Highly Adherent Diamond-like Carbon Coating
The Delphi Batch Process for Highly Adherent Diamond-like Carbon Coating is a batch process for forming diamond-like carbon coatings on three-dimensional parts. One key benefit is the low cost derived from a batch process, without the need for part rotation or target manipulation (no "line-of-sight" restriction). Another key benefit is that the coating is highly adherent, compared to other approaches to form DLC coating. In addition, the substrates are not heated to high temperatures during the coating process. Aluminum components with DLC are more resistant to scuffing and wear. This diamond-like coating also can enhance biocompatibility and durability in biomedical applications such as replacement hip or elbow joints. The coatings are extremely thin, hard, chemically inert, and wear resistant. They have low friction and controllable electrical resistivity and are smooth and adherent.
This is a batch process for forming diamond-like carbon (DLC) coatings on threedimensional
parts. One key benefit is the low cost derived from a batch process, since there is no need
for part rotation or target manipulation (no “line-ofsight” restriction). As an example, 100 pistons could be uniformly coated at one time. Another key benefit is the coating is highly adherent compared to other approaches to form DLC coating. And the substrates are not heated to high temperatures during the coating process.
