What is the coating inside a regular incandescent light bulb?

The coating inside a regular incandescent light bulb is made of tungsten. This coating is what emits light when an electric current passes through it, heating up the tungsten filament to produce light.


What is the function of electron gun?

An electron gun is a device that emits a focused beam of electrons. It is commonly used in cathode ray tubes (CRT) in TVs and computer monitors to generate images by directing the electron beam onto a phosphor-coated screen, causing it to light up and produce images.


What are breaker points made out of?

Breaker points are typically made from materials like tungsten or a tungsten alloy due to their high melting point and excellent conductivity. These materials are chosen for their durability and ability to withstand the wear and tear of opening and closing electrical circuits in ignition systems. Some points may also have a contact surface coated with materials like platinum to improve longevity and performance.


What is a fluorescent screen?

A fluorescent screen is a surface coated with a phosphor material that emits visible light when struck by electrons. It is commonly used in cathode ray tubes (CRTs) and other types of electronic displays to convert electrons into visible light, allowing images or text to be displayed.


Is Tungsten Carbide coated with a layer of high silicon glaze for an outer hull a layer of homemade aerogel insulation and an aluminum inner hull a good combo to use as a space ship hull?

No, the aluminum has to me thick, so you aren't saving anything. The Tungsten Carbide is the 2nd heaviest armor out there. There is two new no metal armor with the new plastic shield with Reinforced byTitanium to help keep hull shape. The mass is cut to less then 25% and less then half the thickness.

Which metal gets coated during electroplating?

The cathode gets coated during electroplating.


In electrolysis of dilute silver chloride what is discharged at the cathode?

I think the cathode will be coated in silver.


Is there a drill bit that drills through stainless steel?

Yes, there is. You use a tungsten or cobalt coated drill bit for this.


What metal gets coated during electroplating?

The metal to be coated is referred to as the "working" or "substrate" metal. During electroplating, it acts as the cathode in the electrolytic cell where the plating process occurs. The metal ions from the plating solution are deposited onto the working metal to form a thin, uniform coating.


What is the best drill bit for hardened steel?

Coated carbide is the best. Uncoated is next.


Should I use a diamond grinding wheel for cutting ceramic tile?

Use a wheel specifically rated for grinding concrete or ceramic tile. It doesn't have to be a diamond wheel; titanium-coated, tungsten-coated or carbide coated wheels will also work.


Why was the X-ray invented?

It was accidentally discovered by William Conrad Roentgen Nov. 8, 1895....he was experimenting with a cathode ray tube when i glass plate coated with barium platinocyanide glowed, the first xray ever taken was of his wifes hand and the exposure took 30 minutes to make


How is the white spot formed on the screen of a cathode ray oscilloscope?

The screen is coated in a thin layer of phosphorous. This glows when bombarded by electrons.


What is the toxic chemical inside cathode ray tubes?

Cadmium, Phosphor material and Lead coated glass of CRT that's so TOXIC.


What are the rays in the cathode ray tubepositive or negative or neutral?

The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.


What are uses for tungsten?

There are many uses for tungsten: Incandescent light bulbs: It makes up the filament of the bulb. It is used in the bulb because it can withstand extreme temperatures. Jewelry: The high scratch resistance and dark shine of tungsten makes it a very popular choice among men for rings and bracelets. Abrasive Coating: Many tools subject to cutting hard metals in harsh conditions are coated with tungsten. The high melting point and hardness of tungsten make it a valuable asset to machinery and cutting tools.
