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
The average daily refund of 30,000 tickets at Beijing Station is the main reason
The average daily refund of 30,000 ticket holders at Beijing Railway Station was due to diesel generators | diesel generators price / 2013-01-25
It is reported that the Spring Festival is about to open. Usually this period is difficult to get a ticket, but at the Jinan Railway Station in Shandong, the person who returned the ticket has stood three floors and three floors outside. An interview with the reporter found that the new ticketing channels gave birth to the “ticket holder†family.
The reporter saw in the ticket hall of Jinan Railway Station that the number of people who came to the station window to buy tickets was a lot less than the same period of last year. The average number of people before each ticket window was less than 10, but there were long lines before the two refund ticket change windows. A passenger who is refunding a ticket took two tickets. He told reporters that on the day of the sale of the ticket, he had booked online for two days to Chengdu, and now the journey is determined and it is decided to return one ticket.
Refunding passengers: At that time, I did not know when the unit would be able to go on vacation. I feared that the booking was delayed and that it was difficult to buy a ticket to Chengdu. I booked two tickets on the 29th and 31st from the Internet.
The reporter roughly estimated that there are about 200 people waiting in line at the refund window. The main reason for their refunds is that they are afraid to buy tickets, so they have booked multiple tickets for different trips to protect the bottom. Mr. Zhang, who was refunding the bills, calculated an account. Compared with the small refund fee, he took the ticket first and was more suitable for himself.
Mr. Zhang: The total price of the hard-covered bed is more than 400, and now the refund fee is a few ten dollars. But if you can't buy tickets, the cost will not be so much.
In a random interview with the reporter, it was found that such "preparedness" passengers were not small, many people were on the phone, the Internet, and the ticket window was a three-pronged approach.
Refunding passengers: To prevent the purchase of tickets, so I bought one again. I will refund the ticket now.
Reporter: Can you buy a ticket if you are back now?
Refund passengers: I bought the ticket today.
According to Jinan train station staff, the number of refunded passengers in the ticket office during the past few days is twice as long as that of the ticket-buying team, and the majority of these are similar to the “ticket†ticket.
Staff: According to statistics, the number of refunds for us in these two days is about 1,800.
This Spring Festival, the first "ticket" has become a lot of people's ticket remedies, station staff said that from January 7 on sale of pre-sale spring ticket, Jinan Railway Station successfully booked 241,900 tickets by telephone, including 9.02 10,000 tickets did not collect tickets in time, resulting in invalid orders. On the one hand, the order is void, and on the other side, the passengers who line up at the ticket window cannot buy the ticket. It is easy to disturb the order of tickets and to cause unnecessary trouble. Not only Jinan, Beijing station also encountered a large number of refund families, Beijing's four stations daily average refunds reached 30,000, the railway department reminded that reservation ticket does not take orders will be automatically canceled, many bookings may not receive tickets may Blacklisted.
Railway department staff: If you go through the booking process after 12 o'clock on the same day, you need to complete the ticket collection procedure by 24 o'clock on the following day. If you do not pick up the ticket in time, the order number will be automatically cancelled by the system.
The reporter learned that the canceled ticket and the passenger’s refund will be immediately returned to the online ticket bank. Therefore, a passenger who does not have a suitable ticket can attempt to try it through other ticketing methods and may encounter a suitable "return" ticket.
