comparison and chemical analysis of various types of anodic aluminum oxide (AAO) finishes produced from conventional electrolytes and those produced from an electrolyte modified with electroactive polymer determined differences, which explain superior bonding performance by the AAO produced from the modified electrolyte. An extensive study comparing
oxide, commonly referred to as alumina, possesses strong ionic interatomic bonding giving rise to desirable material characteristics. It can exist in several crystalline phases which all revert to the most stable hexagonal alpha phase at elevated temperatures. This is the phase of particular interest for structural applications
We have investigated the surface activated bonding (SAB) of deposited Al2O3 films by chemical vapor deposition under a short-time activated condition
oxide of progressive stoichiometry, such as cobalt oxide, which forms an inner divalent oxide layer and an outer trivalent oxide layer 2O 3). Network-modifying oxide growth is attributed to outward metal ion migration to the oxide-electrolyte interface, which forms, unlike the passive on aluminum, a defective

coatings are extensively used in various industries (e.g., automotive, aerospace) to protect the aluminum surface against corrosion. A crucial parameter determining the lifetime of coated metals is the durability of the bonding, in which a clear understanding of molecular-level interfacial chemistry lacks due to the challenges in probing the

All grades will bond aluminum well. For very high strength use a metal bonder such as 170 or the original For bonding aluminum to dissimilar surfaces with different coefficients of thermal expansion consider toughened 737. Single component epoxies are ideal for bonding aluminum. Consider ES550 or
The concentrations of aluminum in tissues of female New Zealand rabbits exposed to dust at a concentration of 0.56 mg m for 5 months (8 5 were determined. The amount of aluminum in the brains of the animals was nearly two and a half times as high as that of the control
anodizing, the aluminum is immersed in various concentrations of acids (usually phosphoric or chromic) while an electrostatic charge is applied. The oxide reacts with the etchant to form a compound that protects the surface and is compatible with the adhesive. In this way, the aluminum oxide is retained but is rendered more receptive to

Disclosed is a method for bonding stainless steel to aluminum oxide. The method includes the steps of providing a first substrate of the stainless steel, filling solder in the first substrate, providing a second substrate of the aluminum oxide, filling solder in the second substrate, providing a net, pressing the net, locating the net between the first and second substrates to form a laminate
layer comprising aluminum is formed over the titanium layer. An oxide component is bonded to the aluminum layer. In accordance with another aspect, the invention is a method of bonding a component to an aluminum metalization layer on a silicon substrate including a cavity formed in a major
Bonding with Active Solders Aluminum is the material of choice for many components and applications today. However the bonding of aluminum presents a challenge due to its naturally forming oxide skin. This nascent oxide skin, Al2O3, exists on all aluminum alloys and serves a natural barrier to corrosion. Unfortunay it also serves
