By alloying several percent of carbon with a minimum, 12 % alloy (primarily chromium), hard carbides are formed and dispersed throughout the surfacing deposit.
These dispersed carbides are much harder than the surrounding matrix and provide excellent abrasion resistance. They are used when the primary wear factor is abrasion. At the lower end of the carbon range (less than 3 %) the quantity of carbides is small compared to the matrix where they are dispersed.
These alloys exhibit good abrasive wear resistance while retaining good toughness. These carbide-surfacing alloys are used to resist a combination of abrasion and impact. As the carbon content increases (to as much as 7 %), in the carbide containing alloys, the abrasion resistance increases and the toughness decreases. This is due to the higher percentage of carbides. As carbides are undermined and knocked out by moving abrasive particles, additional carbides are uncovered to further resist abrasives and delay wear as shown in the diagram to the right.
The low carbon steel base plate enables the plate to be welded, bolted or studded to existing structures, while the hard facing provides the premier wear-resistant surface capable of working in all applicable service conditions at either ambient or elevated temperatures.
HP Wear Resistant Group offers various products of wear plates namely Cr-Carbide Weld Clad Plates, Smooth Surface CCO plate, Heat Treated Wear Plates (AR Plate or Q&T Steel), Casting Plates, Tungsten Carbide Coated Plates in various grade and multiple size options.

How can a crop canopy analyzer achieve nondestructive measurements?
Generally speaking, research on plant physiology usually requires a series of physical and chemical experiments. Therefore, damage to plants is unavoidable. However, with the development of agriculture and advancement of science and technology, areas like agricultural detection have been proposed. The higher requirement is to ensure both the accuracy and the non-destructive determination. Here is a crop canopy analyzer.
To say how a crop canopy analyzer can achieve a non-destructive test, it also refers to the structure and measurement principle of a crop canopy analyzer. The crop canopy analyzer is mainly composed of sensors and controllers and transmits data wirelessly. The sensor is an important part for obtaining information, and it is also the key to the measurement work. It contains the optical part and the circuit part. The optical part contains the optical channel and the photodetector. The optical channel is used to measure the reflected light of solar radiation and crop canopy. The circuit part is composed of power supply, amplifying unit and wireless transmission module. During the measurement process, the crop canopy analyzer can convert light signals into electrical signals so that the information can be determined without damaging the crop.
Crop canopy analysis is an important step in the study of plant canopy light energy resources in current ecology. It is necessary to determine the interception of light in the canopy of plants, and it is important for the relationship between crop growth, yield and quality, and light energy utilization. significance. In order to achieve a non-destructive measurement, the crop canopy analyzer continuously optimizes the traditional measurement method. While using the excellent part of the traditional measurement method, it continues to innovate, and studies the means that can be quickly and non-destructively measured using the instrument, which not only enables crop canopy analysis. It's simpler and it also meets the needs of modern field measurements. At present through comparative experiments in the field, the results show that the crop canopy analyzer can achieve good results, can meet the needs of the current crop canopy non-destructive determination, and through the preservation and transmission of data, to further study the light energy of crops Utilization provides important data materials.
