Description

(54) ОБРАЗЦОВАЯ МЕРА ТВЕРДОСТИ(54) SAMPLE HARDNESS MEASURE

II

Изобретение относитс  к измерительной технике, а именно к образцовым средствам поверки приборов дл  измерени  твердости.The invention relates to a measurement technique, in particular to exemplary means of checking instruments for measuring hardness.

Известны образцовые меры твердости в виде плиток, изтотовленных из низколегированных конструкционных сталей, углеродистых и легированных инструментальных сталей , цветных сплавов на алюминиевой и медной основе и других материалов 1.Exemplary measures of hardness are known in the form of tiles made of low-alloy structural steels, carbon and alloyed tool steels, non-ferrous alloys on aluminum and copper base, and other materials 1.

Данные мерами твердости осуществл ют неполный контроль шкал твердости и, в частности, нижних их пределов.These hardness measures provide incomplete control of the hardness scales and, in particular, their lower limits.

Наиболее близкой по технической сущности к изобретению  вл етс  образцова  мера твердости, содержаща  плитку стандартную дл  поверки приборов дл  измерени  твердости из бескислородной меди твердостью пор дка 42 единиц НВ 2.The closest to the technical essence of the invention is an exemplary measure of hardness, containing a tile standard for calibrating oxygen-free copper hardness testers with a hardness of about 42 HB 2 units.

Однако материал указанной плитки не может быть применен, в частности, дл  образцовых мер твердости, обеспечивающих контроль нижнего предела твердости 8- 35 единиц по щкале Бринелл  из-за более высокой твердости.However, the material specified tiles can not be applied, in particular, for exemplary measures of hardness, providing control of the lower limit of hardness 8-35 units on the Brinell scale due to the higher hardness.

Цель изобретени  - обеспечение единства и точности измерени  твердости м гких металлов и сплавов.The purpose of the invention is to ensure the unity and accuracy of measuring the hardness of soft metals and alloys.

Это достигаетс  тем, что плитка выполнена из алюмини  твердостью 15-30 единиц НВ с толщиной наклепанного сло  0,05 - 0,2 мм.This is achieved by the fact that the tile is made of aluminum with a hardness of 15-30 units HB with a thickness of a peeled-on layer of 0.05-0.2 mm.

Алюминий обеспечивает низкую твердость при малом размахе значений твердости , а относительное вм тие металла по кра м отпечатка не превосходит 4-х процентов . Тонкий наклепанный слой металла с мелкозернистой структурой образует более правильную форму краев отпечатков и устран ет вм тие металла вокруг них.Aluminum provides low hardness with a small range of hardness values, and the relative indentation of the metal at the edges of the print does not exceed 4 percent. A thin, riveted metal layer with a fine-grained structure forms a more regular shape of the edges of the prints and eliminates the penetration of the metal around them.

Цредлагаемые меры твердости выполн ют в виде плиток в соответствии с ГОСТ 9031-75.The proposed hardness measures are in the form of tiles in accordance with GOST 9031-75.

Использование предлагаемых образцовых мер твердости повышает точность измерени  твердости м гких металлов и сплавов на величину допускаемой погрешности приборов.The use of the proposed exemplary measures of hardness improves the accuracy of measuring the hardness of soft metals and alloys by the value of the permissible error of the instruments.
