A comparative study on the dry sliding wear behaviour of nitrocarburised, gas nitrided, fluidised-bed nitrided, and plasma nitrided plastic mould steel
(2016-01-01)
Plastic injection moulds suffer wear due to the relative movements of the mould parts and the polymeric material flow which is often reinforced by hard abrasive fibres or whiskers. Several studies were performed on the ...
A comparative investigation of the corrosion and tribocorrosion behaviour of nitrocarburized, gas nitrided, fluidized-bed nitrided, and plasma nitrided plastic mould steel
(2018-01-25)
The present study aims to compare the corrosion and tribocorrosion behaviour of nitrocarburized, gas-nitrided, fluidized-bed nitrided, and plasma-nitrided Impax Supreme (equivalent to AISI P20) pre-hardened plastic mould ...
Adhesion between polypropylene and steel by over moulding
(2011)
In this work, a hybrid polypropylene (PP)/steel car part (Traverse leg) was created by over moulding. PP was modified with 10%wt. of PP-g-Ma coupling agent. Different surface treatments were applied to the steel determining ...
