Изобретение относитс к контролю качества проведени технологических процессов, в частности к контролю качества тёрмомарнитной обработки, и может быть использовано в производстве посто нных магнитов,.The invention relates to the quality control of technological processes, in particular, to the quality control of thermo-magnetic processing, and can be used in the production of permanent magnets.
Известен способ оценки термомагНитной обработки качества методами металлографического анализа, в частности микроструктуры 1.There is a method for evaluating thermo-magnetic quality processing by methods of metallographic analysis, in particular, the microstructure 1.
Недостатками данного устройства вл ютс трудоемкость процесса изготовлени микрошлифов и отсутствие количественных оценок качества термомагнитной обработки, что ограничивает их применение в производственных услови х .The disadvantages of this device are the laboriousness of the production of microsections and the lack of quantitative assessments of the quality of thermomagnetic processing, which limits their use under production conditions.
Известен также способ контрол качества термомагнитной обработки, ос ованный на измерении одного или нескольких магнитных параметров в направлении магнитной текстуры магнита, прошедшего обработку. Такими параметоами обычно вл ютс остаточна ийдукци , коэрцитивна сила и максимальна удельна магнитна энерги , о качестве термомагнитной рб- . работки суд т по абсолютному значениюперечисленных выше параметров 21.There is also known a method for controlling the quality of thermomagnetic processing, based on the measurement of one or several magnetic parameters in the direction of the magnetic texture of the magnet that has been processed. Such parameters are usually the residual educt, the coercive force and the maximum specific magnetic energy, about the quality of the thermomagnetic RB. the work is judged by the absolute value of the parameters listed above 21.
Недостатком известного способа контрол качества термомагнитной обработки по магнитным параметрам посто нного магните, прошедшего обработку , вл етс то, что абсолютные The disadvantage of the known method of controlling the quality of thermomagnetic treatment according to the magnetic parameters of a permanent magnet that has been processed is that the absolute
10 значени его Магнитных параметров завис т не только от качества технологического процесса, но и от других факторов , например от химического состава сплава, и, следовательно, не The 10 values of its Magnetic Parameters depend not only on the quality of the technological process, but also on other factors, such as the chemical composition of the alloy, and, therefore, not
15 могут служить достоверной оценкой качества термомагнитной обработки.15 can serve as a reliable assessment of the quality of thermomagnetic processing.
Цель изобретени - получение достоверной оценки качества термомагнитной обработки посто нных магнитов The purpose of the invention is to obtain a reliable assessment of the quality of thermomagnetic processing of permanent magnets.
20 из магнитотвердых материалов.20 of hard magnetic materials.
