(1) Tyre pressure (referred to as "tire pressure") should be checked frequently to avoid over- or under-pressure. Too low tire pressure will increase the abnormal wear of tires and increase fuel consumption. Excessive tire pressure can cause early tire wear and puncture. The standard value of the tire pressure should be referred to the "Operating Instructions" of the supporting vehicle, and the tire pressure should be checked at least once a month or before each long-distance trip, including spare tires. (2) The tire pressure should be checked in the condition of cold tyres, that is, it should be checked at least 3 hours after parking. If necessary, the tyre pressure can be added to the pressure specified on the car sign board. (3) Hot tyres are forbidden to be deflated or decompressed. It is normal that the tyre pressure exceeds the specified cold inflation pressure after the tyre has been warmed up. If the tyre pressure of the tyre is reduced, the tyre pressure after cooling will be insufficient. (4) It is recommended to fill with nitrogen. Nitrogen filling prevents punctures and improves driving safety. At the same time, it maintains tire pressure lasting stability, protects rims, prevents slow deflation, reduces tire noise, and improves ride comfort. Nitrogen-filled gas can also extend the service life of the tire, and it can save 2% to 10% of the fuel compared to filling the air. After trying to fill with nitrogen, the operator will obviously feel light, comfortable and tire noise. (5) Use a high-quality barometer to check the tire pressure. Don't just believe in your own eyes. Can't judge whether the inflation pressure of the tire is correct from the appearance. In addition, if the tire leaks for a long time, check the valve first. (1) When used normally, the tread pattern (abbreviated as "caterpillar") will exhibit regular loss. When the tire tread is worn out, it is best to check the front torsion of the tire at the service center (station). The car was parked on a flat road surface, the steering wheel was upright, and people were standing 5 to 10 m in front of the car. Observing the tilt angle of the tire carefully, if the deviation was found to be large, it indicated that the flower had appeared eccentric wear. If the pattern of the tire was not worn, This indicates that the problem is very serious, especially in the event of emergency braking, a puncture may occur. Therefore, it has been found that such problems must be dealt with in a timely manner. The internal and external inclinations of the rear axle should be checked, and tires should be promptly changed if problems are found. After the vehicle has traveled for a period of time, it is best to go to a professional car repair shop for four-wheel alignment. (2) When the tire tread wears to the extreme position, it must be replaced. If the tire wear indicator in the groove shows that the groove depth remains less than 1.6 mm, ask your tire dealer to replace the tire. The tire wear indicator mark is a protrusion in the groove, and when the tread wears to 1.6 mm, it is flush with the tread. If the remaining depth of the tire groove is less than 1.6 mm, there will be the possibility of rain traction and loss of braking force and snow traction. In addition, attention should also be paid to removing hard inclusions such as gravel in the middle of the pattern at any time. To avoid overload, you should also pay attention to the load balance to avoid excessive tire load on one side. In addition, the tire load is closely related to the tire pressure. When the load is large, the tire pressure should be increased within the specified range. Try to choose a good road. When starting a vehicle, it should be kept as steady as possible. During driving, try to maintain moderate speed, gentle acceleration, deceleration at the detour, and avoid sharp steps. In particular, attention should be paid to minimizing the number of emergency brakes. After muddy roads, the dirt on the mudguard should be cleaned in time to reduce the friction on the tires. (1) Routine inspections or self-tests should be performed on the tires during seasonal maintenance. The items include whether the tires have bulges, cracks, cuts, punctures, and abnormal wear. These phenomena must be stopped. Professionals are required to inspect and replace them. (2) Regularly check the tread groove depth of the tread to ensure that its depth is greater than 1.6 mm. Otherwise, new tires () should be replaced in time. Excessively worn tires will cause deterioration in running performance and risk of slipping. (3) Check the tire surface for irregular wear. Due to the different installation positions of the driving wheels and the steering wheels, the nature of the stress is also different, and the wear of the tire is not uniform. In order to prevent abnormal vibration, noise, and extend the service life of tires, proper tire replacement should be used. (4) When replacing tires, it is best to replace them in pairs. The deepest tires are best fitted on the front wheels. In the same vehicle, tires with the same structure, size and pattern should be used as specified. Tungsten carbide mixed Metal Alloy Powder is commonly used in PTA (Plasma Transferred Arc) welding. PTA welding is a process that involves the deposition of a hardfacing material onto a base metal to provide wear resistance, corrosion resistance, and improved mechanical properties.

Tungsten carbide is a very hard and wear-resistant material, making it ideal for applications where high abrasion resistance is required. It is often mixed with other metals, such as nickel, cobalt, or chromium, to form a metal alloy powder. These metal alloys enhance the properties of the tungsten carbide and improve its compatibility with the base metal.
The tungsten carbide mix metal alloy powder is typically fed into the PTA welding torch, where it is melted and propelled onto the surface of the base metal using a high-energy plasma arc. The molten powder forms a hard, dense coating that bonds with the base metal, providing excellent wear resistance and protection.
The specific composition of the tungsten carbide mix metal alloy powder can vary depending on the application requirements. Different ratios of tungsten carbide and other metals can be used to achieve desired properties, such as hardness, toughness, and corrosion resistance.
Overall, tungsten carbide mix metal alloy powder is a versatile and effective material for PTA welding, offering superior wear resistance and protection for various industrial applications.
