Deformasyon Kusurlar\u0131n\u0131n Nedenleri<\/h2>\n

1. Preslenmi\u015f \u00fcr\u00fcn\u00fcn e\u015fit olmayan yo\u011funlu\u011fu: Bu, sinterleme s\u0131ras\u0131nda e\u015fit olmayan b\u00fcz\u00fclmeye yol a\u00e7ar. Daha y\u00fcksek yo\u011funlu\u011fa sahip alanlar daha az b\u00fcz\u00fcl\u00fcrken, daha d\u00fc\u015f\u00fck yo\u011funlu\u011fa sahip alanlar daha fazla b\u00fcz\u00fcl\u00fcr.<\/p>\n

2. Preslenmi\u015f par\u00e7an\u0131n etraf\u0131ndaki karbon atmosferinin dengesiz olmas\u0131: Bu durum \u00fcr\u00fcn\u00fcn deformasyonuna neden olur.<\/p>\n

3.Sinterleme s\u0131ras\u0131nda dengesiz s\u0131cakl\u0131k ortam\u0131: Preslenmi\u015f ham par\u00e7a, sinterleme ortam\u0131ndaki s\u0131cakl\u0131k tutars\u0131zl\u0131klar\u0131 nedeniyle deforme olur.<\/p>\n

4.Di\u011fer nedenler: Sinterleme teknesinin uygunsuz y\u00fcklenmesi, taban plakas\u0131n\u0131n d\u00fczg\u00fcn yerle\u015ftirilmemesi, vb.<\/p>\n

Hafif vakalarda, bir \u00e7atlak a\u011f\u0131 olarak g\u00f6r\u00fcl\u00fcrken, \u015fiddetli vakalarda k\u00fc\u00e7\u00fck par\u00e7alar soyulabilir. A\u015f\u0131r\u0131 vakalarda, \u00fcr\u00fcn \u00e7atlayabilir ve tamamen soyulabilir, soyulma yerlerinde pamuk benzeri karbon siyah\u0131 birikintileri a\u00e7\u0131k\u00e7a g\u00f6r\u00fclebilir.

2.Vakumlu mum giderme a\u015famas\u0131: Mum giderme s\u0131cakl\u0131\u011f\u0131 400\u00b0C'yi (tipik olarak 375\u00b0C) a\u015farsa, parafinin piroliz s\u0131cakl\u0131\u011f\u0131na ula\u015f\u0131r ve d\u00fc\u015f\u00fck molek\u00fcler a\u011f\u0131rl\u0131kl\u0131 parafin, olefinler ve serbest karbon \u00fcretir. S\u0131cakl\u0131k artmaya devam ettik\u00e7e, parafin pirolizi yo\u011funla\u015f\u0131r. Bu a\u015famada, sinterlenmi\u015f g\u00f6vde g\u00f6zenekli ve gev\u015fek hale gelir, mukavemetini \u00f6nemli \u00f6l\u00e7\u00fcde azalt\u0131r ve parafin pirolizi taraf\u0131ndan \u00fcretilen hidrokarbon gazlar\u0131n\u0131n etkisine dayanmas\u0131n\u0131 zorla\u015ft\u0131r\u0131r ve soyulmaya yol a\u00e7ar.<\/p>\n

Ciddi durumlarda, \u00fcr\u00fcn dokunuldu\u011funda ya\u011flanm\u0131\u015f hissedilebilir ve siyah izler b\u0131rakabilir. Karb\u00fcrizasyon genellikle \u00fcr\u00fcn\u00fcn performans\u0131n\u0131 etkiler ve belirli s\u0131n\u0131fa ve ama\u00e7lanan kullan\u0131ma g\u00f6re de\u011ferlendirilmelidir. Uygun olmayan \u00fcr\u00fcnler yeniden i\u015flenmek \u00fczere \u00fcretim birimine iade edilmelidir.<\/p>\n

Karb\u00fcrizasyonun Nedenleri<\/h2>\n

Dekarb\u00fcrizasyon genellikle \u00fcr\u00fcn\u00fcn performans\u0131n\u0131 etkiler ve dekarb\u00fcrize karb\u00fcr \u00fcr\u00fcnleri yeniden i\u015flenmek \u00fczere \u00fcretim birimine geri g\u00f6nderilmelidir.<\/p>\n

Dekarb\u00fcrizasyonun Nedenleri<\/h2>\n

1.Hidrojen sinterlemesi s\u0131ras\u0131nda dekarb\u00fcrizasyon reaksiyonu<\/h3>\n

\u00dcr\u00fcndeki WC ile H\u2082 aras\u0131ndaki reaksiyon CH\u2084 \u00fcretir. Bu reaksiyon sinterleme s\u00fcreci boyunca ger\u00e7ekle\u015fir ve s\u0131cakl\u0131k artt\u0131k\u00e7a yo\u011funla\u015f\u0131r.<\/p>\n

F\u0131r\u0131n giri\u015finde, tam b\u00fcz\u00fclme ger\u00e7ekle\u015fmeden \u00f6nce, \u00fcr\u00fcnde hem i\u00e7ten hem de d\u0131\u015ftan dekarb\u00fcrizasyon meydana gelir.<\/p>\n

F\u0131r\u0131n \u00e7\u0131k\u0131\u015f\u0131nda, \u00fcr\u00fcn b\u00fcz\u00fcld\u00fckten sonra y\u00fczeyde dekarb\u00fcrizasyon meydana gelir.

H2O+WC\u2192W+H2+CO<\/p>\n

H2O+C\u2192CO+H2<\/p>\n

Bu reaksiyon f\u0131r\u0131n\u0131n hem giri\u015finde hem de \u00e7\u0131k\u0131\u015f\u0131nda meydana gelir. Tam b\u00fcz\u00fclmeden \u00f6nce i\u00e7 ve d\u0131\u015f dekarb\u00fcrizasyona neden olurken, f\u0131r\u0131n \u00e7\u0131k\u0131\u015f\u0131nda y\u00fczey dekarb\u00fcrizasyonuna neden olur.<\/p>\n

Vakum sinterleme s\u0131ras\u0131nda dekarb\u00fcrizasyon reaksiyonu<\/p>\n

Vakum sinterleme s\u0131ras\u0131nda deoksidasyon reaksiyonu, preslenmi\u015f blank\u0131n oksijen i\u00e7ermesi nedeniyle meydana gelir ve bu oksijen sinterleme s\u0131ras\u0131nda serbest karbon ve WC'deki karbon taraf\u0131ndan indirgenir. Reaksiyonlar \u015funlard\u0131r:<\/p>\n

MeO+C\u2192Me+CO<\/p>\n

MeO+2C\u2192MeC+CO<\/p>\n

This reaction also occurs at both ends of the furnace entry and exit. Before complete contraction, the U-shaped product causes decarburization both inside and outside. At the exit end, it causes decarburization on the product’s surface.<\/p>\n

2.Vakum sinterleme dekarb\u00fcrizasyon reaksiyonu<\/h3>\n

Vakum sinterlemesinden sonra deoksidasyon reaksiyonu, kompakt\u0131n sinterleme s\u0131ras\u0131nda serbest karbon ve WC'deki karbon taraf\u0131ndan indirgenen oksijen i\u00e7ermesi nedeniyle meydana gelir. Reaksiyon: MeO + C == Me + CO, MeO + 2C == MeC + dekarb\u00fcrizasyon reaksiyonu meydana gelmi\u015ftir.<\/p>\n

Mikro yap\u0131da farkl\u0131 derecelerde organizasyon yap\u0131s\u0131 g\u00f6r\u00fclebilir. Karma karb\u00fcrl\u00fc malzemeler performans\u0131 etkiler ve genellikle hurda olarak kabul edilir, ancak hafif kar\u0131\u015ft\u0131r\u0131lm\u0131\u015f malzemeler kesitsel kirlenme standard\u0131na g\u00f6re incelenebilir ve i\u015flenebilir.<\/p>\n

Bu t\u00fcr ala\u015f\u0131ml\u0131 \u00fcr\u00fcn<\/a>, due to insufficient compacting density and excessively large hole size, does not completely disappear during the sintering process. The product’s surface shows loose particles, mainly appearing at the blade edges and corners. In severe cases, fine cracks appear on the surface, and the cross-section shows triangular or strip-shaped holes. If only the surface is slightly poorly pressed, and the cross-section and metallography do not show this phenomenon, it can be released as a qualified product. If the surface is poorly pressed, and the cross-section and metallography also show this phenomenon, then this type of product should be treated as scrap.<\/p>\n

In actual production, there may be various other issues, which require us to further improve our understanding, analyze the causes, and propose specific countermeasures. After the occurrence of non-conformance, it is necessary to seriously analyze our production process, identify the causes, and make improvements. Generally, attention should be paid to details, especially the usual practices that are often taken for granted. Only by truly focusing on the details can we reduce problems and avoid quality issues. Therefore, it is said: “Details determine success or failure.”<\/div>\n

Cemented carbide is a powder metallurgy product primarily composed of micron-sized tungsten carbide powder, a high-hardness refractory metal, with cobalt, nickel, or molybdenum as binders. It is sintered in a vacuum furnace or hydrogen reduction furnace. The production process of cemented carbide is highly complex, and even minor oversights can easily lead to defects.
