Many car owners are not accustomed to driving an automatic car after they finish the manual transmission. They have a lot of experience in driving manual vehicles, such as “neutral gliding†but this will not be used in automatic vehicles. "Vital gliding" destroys the car? The truth turned out to be this way.
When the automatic car driving is very fast, you only need to catch the throttle to reduce the speed, then the problem has arisen. When the engine recovers oil, the speed of the engine decreases, and the speed of the transmission suddenly decreases. What will happen to the engine? I believe that the majority of owners have experience, that is, the speed began to decline, this deceleration is driven by the engine to drive the transmission, then this deceleration will not damage the transmission it? In fact, this is only an extended issue. The question to be asked this time is: "What is the effect of the neutral coasting on the speed change? Will it damage the car's gearbox? What happens to the gearbox when we are engaged in neutral (N)? In fact, it is very simple that the transmission components in the gearbox are idling, that is, the sun gear, planet carrier and ring gear are not fixed by the relevant components. When we engage the N block from the D block, the power of the engine still changes through the hydraulic torque. The transmission to the transmission, that is to say, the transmission's oil pump has been working.Speaking of this there will be many people doubts, before always listening to people saying that when the transmission is in the neutral gear, the transmission is easily damaged because the oil supply and heat dissipation problems are not solved. The fact that the “neutral glide†destroys the car actually turns out to be the fact that the input shaft runs with the sun gear when it is in neutral and drives the planetary gears to rotate. The planetary gears in turn rotate the ring gear, but it is in the neutral gear ring and the planetary carrier. Neither is fixed, the input power is not transmitted to the output shaft, so the governor will not send a rotational speed signal to the transmission oil pump (the oil will not be interrupted), and After the pump is in the torque converter, ie the oil pump is working, at least the pressure inside the gearbox will always be maintained at a basic pressure.The problem is that this basic pressure can not meet the lubrication and heat dissipation of the gearbox. Since the transmission oil pump is able to pump oil, the fact is that the gearbox is not damaged due to lack of lubrication as many people say. (The specific use is based on the manual of the vehicle, and there are differences in different brands of automatic transmissions.)
Regardless of whether your car is an automatic or a manual transmission, the Master recommends that you do not hang a neutral gear when you go downhill, not because the damage does not damage the transmission, but is a matter of personal safety. When the neutral gear is downhill, it loses the effect of braking the engine (some vehicles have a traction control system). The speed will be faster and faster. If unexpected situations occur at this time, the consequences will be disastrous.
Oxide powder for thermal spray refers to a type of powder material that is used in thermal spray processes. Thermal spray is a coating technique where a material in powder form is heated and propelled onto a substrate, forming a coating.
Oxide powders are commonly used in thermal spray applications due to their high melting points, excellent wear resistance, and thermal insulation properties. They can be used to create protective coatings on various surfaces, such as metals, ceramics, and plastics.
Some common types of oxide powders used in thermal spray include:
1. Aluminum oxide (Al2O3): This oxide powder is widely used for its high hardness, wear resistance, and thermal insulation properties. It is commonly used for coating applications in industries such as aerospace, automotive, and electronics.
2. Zirconium oxide (ZrO2): Zirconium oxide powder is known for its high melting point and excellent thermal barrier properties. It is often used in thermal spray coatings for gas turbine engine components, where thermal insulation is critical.
3. Chromium oxide (Cr2O3): Chromium oxide powder is used for its high hardness, corrosion resistance, and wear resistance. It is commonly used in applications where high temperature and abrasive wear resistance are required.
4. Titanium oxide (TiO2): Titanium oxide powder is known for its high refractive index and excellent UV resistance. It is often used in thermal spray coatings for optical and decorative applications.
These oxide powders can be applied using various thermal spray techniques, such as flame spraying, plasma spraying, or high-velocity oxy-fuel (HVOF) spraying. The choice of oxide powder and thermal spray technique depends on the specific application requirements and desired coating properties.
