Abstract
A joined article includes a first component having a laser-treated surface portion and a second component having a laser-treated surface portion. An adhesive joins the first component to the second component at the treated surface portion. A method of making a joined article form components and a system for making joined articles are also disclosed.
Claims7
A joined article, comprising:
- a first component having an interference laser-treated surface portion;
- a second component having an interference laser-treated surface portion;
- and,
- an adhesive joining the first component to the second component at the interference laser-treated surface portions;
- wherein the interference laser-treated surface portions comprise ridge features, wherein the ridge features have a periodicity between 0.5-50 μm, and wherein the periodicity varies by no more than ±5%.
