Reference number : GC-2017-Q4-00401, amendment number : , agreement type : G, recipient legal name : Cree, Duncan (University of Saskatchewan), recipient country : CA, recipient province : nan, recipient city : Saskatchewan, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Adhesively bonding materials can be complex at times due to the boundary between the two materials being_x000D_
joined. Poor bonding can be caused by surface contaminations, improper installation procedures or simply not_x000D_
using the right bonding product. In addition, it is possible that the type of adhesive works well for one material_x000D_
but may not be as effective for a different material._x000D_
The objective of this study will determine if one adhesive can work well for all types of crystal jewelry_x000D_
submitted to different scenarios and if a unique preparation process for the crystals and adhesives are required._x000D_
The research supported by this NSERC Engage Grant will investigate the use of a variety of commercially_x000D_
available adhesives on four crystal types. The adhesive bond strength will be evaluated under different_x000D_
conditions such as: contaminates on the as-received crystal surfaces, epoxy-clay adhesive mixing time, working_x000D_
times and curing temperature. The bonded crystals will also be subjected to temperature fluctuations (+35°C to_x000D_
-35°C) to reproduce real world applications and their bond strength assessed. By employing an optimization_x000D_
technique, the best formulation will be determined for the best bond strength._x000D_
The performance of the selected adhesives will enable recommendations to be made related to their adhesion_x000D_
ability and crystal surface preparation technique. It is anticipated the research will provide a faster, more_x000D_
reliable assembling technique than the previous approach. An innovative, unique step-by-step_x000D_
solution/procedure to provide a high strength bond between jewelry and epoxy-clay adhesives will be provided., program purpose french : Adhesively bonding materials can be complex at times due to the boundary between the two materials being_x000D_
