Aerospace series - Molybdenum disulphide dry film lubricants graphite and halogen free - Technical specification

This standard specifies the qualification and test requirements for graphite and halogen free molybdenum
disulphide dry film lubricant.
Test requirements and testing of fretting, corrosion, wear and friction properties of relevant lubricants are
not part of this standard. Refer to relevant standards in normative references.
All testing defined in this standard has to be certified by the manufacturer of the lubricant.
In order to achieve uniform coatings with defined thickness and best adhesion properties, spray application
in combination with heat curing is recommended.

Aeronavtika - Suha maziva iz molibdenovega disulfida brez grafita in halogena - Tehnična specifikacija

Ta standard določa zahteve glede ustreznosti in preskušanja suhega maziva iz molibdenovega disulfida brez grafita in halogena.
Preskusni pogoji in preskušanje lastnosti fretiranja, korozije, obrabe in trenja ustreznih maziv niso del tega standarda. Upoštevajte ustrezne standarde v normativnih referencah.
Vse preskuse, opredeljene v tem standardu, mora potrditi proizvajalec maziva.
Za dosego enakomernih premazov z določeno debelino in najboljšimi adhezijskimi lastnostmi priporočamo nanašanje pršila v kombinaciji s toplotno obdelavo.
