To provide a structural and durable bond, the adhesion between the CFRP-part and the adhesive has to be guaranteed [6], which is actually the most relevant challenge during the assembly process.
As a durable coating with proper adhesion is needed on the substrate, the effect of stand-off distance (SOD) which is an important parameter of the spray on the microstructure, the hardness and adhesion of the copper coating on the 316L stainless steel were investigated.
The rough surfaces showed durable superhydrophobicity and ultralow water adhesion even after storing in various harsh environment for a long time, including strong acid, strong alkali, and high temperature.
To obtain a durable Ni coating with excellent adhesion strength on an AZ91D Mg alloy, a pretreatment was performed with a small amount of Cu2+ ions added to the activation bath used in the pretreatment prior to the plating process.
The composite coating demonstrates strong adhesion, excellent wear resistance and durable anti-wettability.
The various system components (i.e. clearcoat, basecoat, primer, and electrocoat with steel substrate or adhesion promoter with plastic substrate) must be durable, compatible and integrate with each other to create systems that possess adequate service life performance.
As the scales of the components shrink, adhesion, stiction, friction, and wear become a significant technological barrier for the successful deployment of durable devices.
For example, nylon is a strong, durable, and versatile 3-D printing material, which is both flexible when thin, but has high inter-layer adhesion, which enables it to be used for functional parts such as those needed in a bicycle.
