Ensayos no destructivos de carburo cementado es el nombre general de todos los medios t\u00e9cnicos para utilizar las caracter\u00edsticas del sonido, la luz, el magnetismo y la electricidad para detectar si existen defectos o falta de homogeneidad en el objeto inspeccionado, y para dar informaci\u00f3n como el tama\u00f1o, ubicaci\u00f3n , naturaleza y cantidad de los defectos, a fin de determinar el estado t\u00e9cnico del objeto inspeccionado (como si est\u00e1 calificado o no, vida \u00fatil restante, etc.). Este tipo de tecnolog\u00eda se usa a menudo en la inspecci\u00f3n de calidad de productos de carburo cementado.<\/p>\n\n\n\n
In this blog, we will focus on four nondestructive testing methods of cemented carbide products commonly used in meetyou carbide Company: ultrasonic testing (UT), magnetic particle testing (MT), liquid penetrant testing (PT) and X-ray testing (RT). <\/p>\n\n\n\n
Ultrasonic Testing is one of the common nondestructive testing methods for cemented carbide in industry. When an ultrasonic wave enters an object and encounters a defect, part of the sound waves will be reflected. The transmitter and receiver can analyze the reflected waves, so that the defect can be detected abnormally accurately, and the position and size of the internal defect can be displayed, and the thickness of the material can be measured.<\/p>\n\n\n\n
Advantages of ultrasonic nondestructive testing of cemented carbide:<\/p>\n\n\n\n
1, the penetration ability is large, for example, the effective detection depth in steel can reach more than 1m;<\/p>\n\n\n\n
2. For plane defects such as cracks and interlayers, the nondestructive testing sensitivity of cemented carbide is high, and the depth and relative size of defects can be measured;<\/p>\n\n\n\n
3. The equipment is light, the operation is safe, and it is easy to realize automatic inspection.<\/p>\n\n\n\n
Desventajas:<\/p>\n\n\n\n
It is not easy to inspect alloy workpieces with complicated shapes, so the surface to be inspected must have a certain smoothness, and a coupling agent should be used to fill the gap between the probe and the surface to ensure sufficient acoustic coupling.<\/p>\n\n\n\n
