Provided are a formulation which creates protection layers on the metal friction and wear surface and a method for preparing the same. The formulation provided here comprises 45-99 parts laminar hydroxyl silicate powders, 1-50 parts formulation which creates protection layers on the metal surface and method for preparing the same and 0.05-6 parts carbonization-graphitization catalyst, calculated by weight. Also provided is method for preparing the same. The formulation provided here could create a friction-reducing and wear-resistant nanocrystal protection layer in situ on the metal friction and wear surface, at the same time, it has high hardness of cermet and elastic modulus of formulation which creates protection layers on the metal surface and method for preparing the samehigh grade alloy steel.
L'invention concerne une formulation qui forme des couches de protection à la surface d'un métal sujette au frottement et à l'usure et un procédé pour préparer cette formulation. La formulation de l'invention comprend de 45 à 99 parts de poudres de silicate hydroxylé laminaire, de 1 à 50 parts d'une formulation qui crée des couches de protection à la surface du métal et de 0,05 à 6 parts d'un catalyseur de carbonisation - graphitisation, calculées en poids. L'invention concerne aussi un procédé pour préparer cette formulation. La formulation de l'invention permet de créer une couche de nanocristaux qui réduit le frottement et résiste à l'usure; en même temps, elle possède une dureté nécessaire d'un cermet et un module d'élasticité d'un acier d'alliage spécial.
