Ni-coating was widely used to protect the sintered NdFeB magnet from corrosion by Watt electro-deposition solution. However, the protection failure always occurs due to poor adhesion strength between Ni-coating and NdFeB substrate. In present work, the adhesion strength of the Ni-coating on NdFeB...
However, there is ongoing debate on the precise role of adhesion in coating failure and substrate corrosion. One school of thought, well supported by practice and experiment, is that adhesion plays the dominant role in determining the protectiveness of a coating. Generally stated, the competing ...
4.5 spray for 1-2 times, between each time interval should be longer than 5 minutes, this is because the short easy Super flow ink, coating thin, long easy adhesion between the layers and layers of dust and lead to a decline in coating adhesion. 翻译结果4复制译文编辑译文朗读译文返回顶部 ...
fracture occurs at the interface between layers (coating on dolly face differs from surface). Gluefailure:visible separation of the glue from itself, the coating, or dolly (no coating visible on the dolly face). How do you verify the accuracy of pull-off adhesion testers?
Eliminate adhesion failure in manufacturing by controlling critical surfaces for bonding, coating, sealing, painting, or printing for adhesion quality.
off or the force the dolly withstood, yields the tensile strength in pounds per square inch (psi) or mega Pascals (MPa). Failure will occur along the weakest plane within the system comprised of the dolly, adhesive, coating system, and substrate, and will be exposed by the fracture ...
the dolly or the force experienced by the dolly produces a tensile strength in pounds per square inch (psi) or megapascal (MPa).Failure will occur along the weakest plane in the system consisting of the cart, adhesive, coating system and substrate and will be exposed by the fractured surface...
However, test results (intra-laboratory— the coating specification was tai- done in the same lab, as well as lored to a particular 100% vol- i n t e r-laboratory—a comparison ume solids polyurethane for which the adhesive vs. cohesive failure should be between different labs). The ...
a钢构件涂装后,在4小时之内遇有大风或下雨时,则加以覆盖,防止粘染尘土和水气,影响涂层的附着力 After the steel lumber painting, meets when 4 hours has the gale or rains, then performs to cover, prevented sticks dyes the dust and the moisture, affects the coating the adhesion [translate] ...
the extrinsic factors such as coating thickness and substrate hardness must also be known if the results of the test are to be understood. These parameters, together with the residual stress in the coating and its Young’smodulus, are an important requirement for the models of the failure mode...
