Knoop Sertlik Testine Giri\u015f<\/h2>\n\n\n\n

Bu Knoop sertlik testi<\/strong>\u00f6ncelikle k\u0131r\u0131lgan malzemelerin, ince filmlerin ve k\u00fc\u00e7\u00fck, hassas bile\u015fenlerin sertli\u011fini \u00f6l\u00e7mek i\u00e7in kullan\u0131lan bir mikro indentasyon sertlik testi y\u00f6ntemidir. 1939 y\u0131l\u0131nda Frederick Knoop ve meslekta\u015flar\u0131 taraf\u0131ndan Ulusal Standartlar B\u00fcrosu'nda (\u015fimdi NIST) geli\u015ftirilen bu test, cam, seramik ve de\u011ferli ta\u015flar gibi malzemelere uyguland\u0131\u011f\u0131nda Brinell ve Rockwell gibi mevcut sertlik testlerinin s\u0131n\u0131rlamalar\u0131n\u0131 ele almak i\u00e7in \u00f6zel olarak tasarlanm\u0131\u015ft\u0131r.<\/p>\n\n\n\n

B\u00fcy\u00fck girintiler ve y\u00fcksek y\u00fckler kullanan makro sertlik testlerinin aksine, Knoop testi e\u015fkenar d\u00f6rtgen elmas girinti<\/strong>ve nispeten hafif y\u00fckler (tipik olarak 10 gf ila 1000 gf). Bu, k\u0131r\u0131lgan malzemelerde \u00e7atlamay\u0131 en aza indiren ve numuneye zarar vermeden lokalize sertlik \u00f6l\u00e7\u00fcm\u00fcne izin veren s\u0131\u011f, uzun bir girinti olu\u015fturur.<\/p>\n\n\n\n

Bug\u00fcn, Knoop testi standart olarak ASTM E384<\/strong>(Malzemelerin Mikroindentasyon Sertli\u011fi i\u00e7in Standart Test Y\u00f6ntemi) ve \u00f6zellikle seramiklerin, camlar\u0131n, ince filmlerin ve kaplanm\u0131\u015f y\u00fczeylerin karakterize edilmesi i\u00e7in malzeme biliminde kritik bir ara\u00e7 olmaya devam etmektedir.<\/p>\n\n\n\n
