Japan will promote the use of a new generation of smart meters

Tokyo Electric Power Co. and Kansai Electric Power Co., Ltd. plan to promote next-generation smart meters that can read user power information directly from the meter's “B channel” next year. Users can use the display screen of the HEMS (Home Energy Management System) to know how to use electricity in real time. This method not only makes it easier to save power on the user side, but also makes it easier for the user to set a detailed electricity tariff plan according to the load.

There are three channels A, B, and C for obtaining electricity information from the smart meter. The A-channel is obtained through the power company using the Internet, and the C-channel is obtained through a third party.

The Ministry of Economy, Trade and Industry of Japan will standardize the standards for smart meters and HEMS required interfaces this year to accelerate the unification of data formats provided by power companies. After the completion of these tasks and the development of the corresponding HEMS, the two power companies will begin installing smart meters with B-channel functionality.

Cobalt Alloy Powder

Cobalt-based alloy powders are commonly used in laser cladding processes due to their excellent wear resistance, high temperature strength, and corrosion resistance. These alloys typically contain varying amounts of cobalt, chromium, tungsten, and nickel, among other elements, to achieve specific properties.

The laser cladding process involves melting the cobalt-based alloy powder using a high-energy laser beam and depositing it onto a substrate to form a protective coating. This coating helps to enhance the surface properties of the substrate, such as hardness, wear resistance, and corrosion resistance.

Some common cobalt-based alloy powders used in laser cladding include:

1. Stellite: This is a well-known cobalt-chromium-tungsten alloy that offers excellent wear and corrosion resistance. It is often used in applications where high temperatures and abrasive environments are present, such as in oil and gas drilling tools, valves, and pump components.

2. Tribaloy: Tribaloy alloys are cobalt-based alloys that contain varying amounts of chromium, molybdenum, and silicon. They are known for their exceptional high-temperature strength and resistance to galling, making them suitable for applications in the aerospace, petrochemical, and power generation industries.

3. Haynes alloys: Haynes alloys are nickel-cobalt-chromium-molybdenum alloys that offer excellent high-temperature strength, oxidation resistance, and corrosion resistance. They are commonly used in applications where extreme heat and corrosive environments are present, such as in gas turbines and chemical processing equipment.

These cobalt-based alloy powders are available in various particle sizes and can be tailored to meet specific application requirements. They can be used with different laser cladding techniques, such as powder-fed laser cladding or blown powder laser cladding, depending on the desired coating thickness and properties.

Overall, cobalt-based alloy powders for laser cladding provide enhanced surface properties and improved performa
