Abstract
Изобретение относитс к способам определени микротвердости металлических покрытий, полученных испарением в вакууме. Цель изобретени - повышение удобства при массовом контроле изделий. В способе измер ют шероховатость покрытий, стро т зависимость микротвердости от шероховатости, по которой после измерени шероховатости контролируемых изделий суд т о микротвердости покрытий этих изделий. Дл расширени диапазонов изделий путем определени микротвердости неразрушаемых покрытий шероховатость измер ют оптическим методом.The invention relates to methods for determining the microhardness of metallic coatings obtained by evaporation in a vacuum. The purpose of the invention is to improve convenience in the mass control of products. In the method, the roughness of the coatings is measured, the dependence of the microhardness on the roughness is constructed, according to which, after measuring the roughness of the tested products, the microhardness of the coatings of these products is judged. To expand the product ranges by determining the microhardness of non-destructible coatings, the roughness is measured optically.

Изобретение относитс к определению механических характеристик материалов, в частности к способам определени микротвердости изделий с металлическими покрыти ми , полученными испарением в вакууме, и может быть полезно при массовом контроле изделий.The invention relates to the determination of the mechanical characteristics of materials, in particular, to methods for determining the microhardness of products with metal coatings obtained by evaporation in a vacuum, and can be useful in mass inspection of products.
Цель изобретени - повышение удобства при массовом контроле изделий.The purpose of the invention is to improve convenience in the mass control of products.
Способ реализуетс следующим образом .The method is implemented as follows.
Измер ют микротвердость и шероховатость металлических покрытий образцов с покрыти ми одного вида (металла), полученными по различным технологи м испарени металла в вакууме. Стро т зависимость микротвердости от выбранного геометрического параметра шероховатости. При массовом контроле изделий с данным видом металлического покрыти измер ют шероховатость покрытий и по полученной зависимостиThe microhardness and roughness of metal coatings of samples with coatings of the same type (metal), obtained by various evaporation technologies of metal in vacuum, are measured. The dependence of microhardness on the selected geometric roughness parameter is constructed. During mass control of products with this type of metal coating, the roughness of the coatings is measured and according to the obtained dependence
микротвердости от шероховатости определ ют микротвердость контролируемого покрыти .microhardness of the roughness determine the microhardness of the controlled coating.
С целью расширени диапазона контролируемых изделий путем определени микротвердости покрытий с неразрушаемой поверхностью шероховатость покрытий определ ют оптическим методом.In order to expand the range of controlled products by determining the microhardness of coatings with an indestructible surface, the roughness of the coatings is determined by an optical method.
